Love how Simon complained about the first one being too mild and then the rest were literally all massacres

13:59 We all saw Harry laughing but I am surprised that JJ didn’t say anything.

The face Harry made when he clocked the guys last name 😂 13:49

Simon looked devastated watching this after the first one P.S. Harry’s face at 13:47 when he said that name 😂

Parties that went wrong : when Phil arrived at Josh’s birthday party in the sidemen video 😂😂

"I went to a party and I slept with none of them" *Typical JJ Failure*

harry trying so hard to not laugh at the woman's name lmao 13:58

13:47 i love Harry's reaction when he heard the name😂😂😂😂

harry's face at 13:47 💀

13:48 The smile in Harry's face 😂

"Marinate the chicken and choose the one to eat" ~ JJ 2021 It's literally a new quote every week

Bloody hell this is dark

I thought they were gonna say "Oops! Silly guy! He's sleeping with his face in dog crap!" But they were like "a guy didn't like these people very much, so he shot everyone and lit the house on fire"

Simon looks like he's having a crisis throughout the entire video 😂😂😂😂😂

JJ: It's all about being able to marinate a chicken and pick who you actually want to eat. Me watching the video: Seems about right. Is it really a sidemen video without JJ doing his thing?

13:46 HARRY CLOCKED IT AS WELL AHAHAHAHA WHY DID JJ NOT REACT TO IT 😂😂😂😂

13:47 Harry’s face😭😭

13:48 harry was waiting for jj to react, 14:01 harry failed to keep it in

That last second switch up of KSI talking about his party experience saved him from sleeping on the couch for a week 😂

At the retirement party of my aunt, a doctor that worked with her for years (maybe decades) hugged her so hard and for so long, jokingly, that he broke her spine. He himself diagnosed her with osteoporosis only months before. She didn’t have spinal damage, but he damaged some nerves. She loves him still btw. 👍 Great party

13:52 this man knew what he was smiling for

well... this wasn't as fun as I thought it would be 😅

All of them: “I didn’t expect it to be about deadly parties” The channel’s name: “They will Kill You”

I swear JJ can change the emotion of an entire video in under 10 seconds 😂😂😂

13:46 look at how Harry reacts to her name, he’s still a kid at heart, bless him

JJ: I think the only thing he should do is a angry tweet 🤣

I’ve been crying all day from uni stress and decided to watch this to cheer me up… didn’t go to plan

I'm new to sidemen & have only been watching for less than a month (seen around 20 different videos). This is easily the quietest I've ever seen a group of you😂🤣

i love how frequent the sidemenreacts videos are. always so entertaining as well

This sidemen Sunday (main sidemen channel) was one of the best. Have been watching for 7 years now never disappoints(first started watching ksi)

the one time JJ pulls a good intro he doggs every other sidemen channel you can't write you lot I love it 🤣🤣

Simon's angry about the first one, but at least it was the only actual big party that went in the intended direction.

I'm shock that the club party incident that was located in the Philippines didn't make it through this video. It was a pre-graduation celebration. Bunch of friends decided to rent a whole club for their college celebration, and in the middle of the celebration, a fire broke out and spreads quickly. Because of panic, people ran to the door, pushing it open but didn't budge because the door was built one way. It was push if you're going in the club, and pull if you want to go out. Students ran towards the door, hoping to save themselves, but they were trapped inside because it was pull door... Those people outside the club tried to open the door but they can't open it because the students inside the club are pushing the door instead of pulling it. Due to the accident that killed a lot of graduating students, the club shuts its business down. However, people said that even though that the club is fully closed, bystanders can still hear the screams of the students that died in the club when the clock strikes at the exact time of the accident. Since then, a famous belief came in. "If you're a graduating student, you should be extra careful because accidents will come to you"

Daily reminder that you are amazing and loved 😊

13:47, Harry's face when the narrator says the 'C' word is absolutely priceless😂😂! It's funny how none of the other lads noticed it😂😂

Harry laughing at the number one entry was brilliant!🤣

13:48 Harry hears the word and starts laughing 😂😂😂 what a guy😂😂💯🙏🏻

I'm sorry but it's always funny when a video turns out to be grim their reactions are hilarious 🤣🤣

I was 12 when the Covina one happened, and one of my good friends in little league lost both his parents in it. Everyone in the league was devastated and we had a memorial at the park for him

That last sidemen Sunday was so good lol thanks boys

People who didn't get invited to these parties and were angry earlier would thank God everyday from that day forth

That guy: dies after being thrown in the air (rip) Harry: totally fine after fallen of his roof twice

Love ya vids guys keep it up!

The way JJ said Van Persia brought back so many memories wow Old KSI will never be topped

I want these man to React most disrespectful drill lyrics by hip hop daily 😂

Rah, that call between the survivor and the emergency services was deep. I had to skip past it. This is a mad video ya know.

This channel almost as good as a fresh sunday church session

This was a lovely start to the day boys. Thanks..

13:45 Harry can't stop laughing but can't say anything😂😂😂😂

13:46 harry trying not to laugh is so jokes

I thought this was gonna be comedic party gone wrong moments 😂😂

Love how only Harry caught on to the last one LOL i was like yoo what did he say, what was his name? Jean what?

You can Never go wrong with a sideman video🔥🔥

This really took a turn from the first one LOL

"It's all about being able to marinate the chicken and then pick which one you want" 😂💀😂💀😂💀😂💀😂💀

Cheers lads this was uplifting

13:49 Harry’s face after hearing the name 😂😂😂

Legends say Simon is still angry about the first one

I think this was a lot more depressing than they ever thought it was gonna be 🤣🤣 sheeeeesh

Harry: "These parties are sh!t" 😂😂

Sidemen really out here thought that Project X donnie is one of the worst parties ever 😂

Why Harry is so surprise about the party that simon gone 🤣

Lmao Simon looked so scared during this video 😭😂

The best 3 sidemen by a mile 🔥

13:49 Harry’s face had me dying.

me(sees the title): ahh video about phill at josh's party😂

"what a lovley start to the day" 😂

the elite trio

Simon: shut down by the police Every 15-19 year old in London: ain’t that how they meant to end?

After the 1st one.. Simon: why is there a skull? Me: you're in for a treat

I LOVE YOUR VIDEOS KEEP GOING

Harry: ohhhh the bloody guns again 😂😂😂

Definitely need more vids like this tho lowkey

These 3 never miss😂🔥

What an outrageous list! Nearly all of them involve death except the first one some people stood atop some house boats. 🙈😂

Well, this has made my day more...... interesting.

LOve how harry tries to keep in laugh

All we need is Harry, Vik and Ethan reacting to ar12 donation montage 2020

Look at Harry’s face at 13:47 😂😂😂😂

I thought this was gonna be a compilation of parties going wrong like someone getting hit in the balls etc

13:47 and 13:59-14:11 harry's career flashed before his eyes 😂

13:49 Harry has me cryingggg 😂😂😂

I agree with JJ at 6:14. The US needs to institute a federal firearm licensing system so as to not only decrease shootings, but even prevent them in advance.

Thought I'd watch a funny video and sleep calmly, seeing the title.Well, that didn't work out. Rip dreams

When JJ in the thumbnail guaranteed JJ in the video

From a floating tv to massacres and murders 0-100 real quick

Went to a bachelor party where the groom to be died from a heart attack during the festivities. R.I.P my G

imagine being invited to a party

I just love how the background music is unnecessarily scary LMAO

the best channel of the sidemen channels

Harrys face at 13:45 😂😂

Channel name "they will kill you" Sidemen saying we didn't expected that from this video

no one clocked how mad simon's "it was a boy at least line was" 😂💀

They should've add the picture of Simon and JJ after sideman pub golf on that couch instead of that pic on the stairs🤣

Simon: why was there a gun Clearly has never been to America where there is literally I gun everywhere. I would say in a lot of places you go, especially the south, more people own a gun than not.

Project X was actually based off of the Aussie legend called Corey Worthington, search up the interview its basically like what project x used at the end of the movie

You guys should react to scary/creepy videos for the month of October, would be sick

Best sidemen channel indeed

Got to say lads love the energy after some pleb chose a depressing video what a mood killer that was all jokes aside next time look for videos like over the top partys or party aftermath

I just want to point out that the footage shown for the gender reveal explosion/fire is actually from arizona that happened almost 3 years ago, and not the California one.
