JJ, this isn’t what we meant by “Activate Windows”

Thanks for reacting to the video! You guys are awesome!!

Jj has a window???

Sidemen: makes a video on refrees fighting Comments: Is ThAt A wInDoW

KSI's room with his window open looks like a whole different room 🤣🤣

“This is Sidemen reacts, we are the Sidemen and we are reacting” 😂 thanks for the explanation Harry

I didn’t even know JJ had a window in his room. It was always covered until now😂

Imagine JJ beats up Jake so bad he starts mistakenly fighting Logan mid-fight 💀

big up them for posting everyday

Ksi has his window open. What a Christmas present for all of us

"Id be coming from the top ropes giving someone an elbow" - KSI @ 7:50 he spoke it into existance

7:46 JJ predicts the future?

Looks like JJ finally activated his room window.

JJ showing his windows for once

0:36 anybody notice how simon and jj were looking at each other whilst conversating, smart editing

11:29 Harry actually said “ come Leon ” when the guy was fighting back ffs 😂😂

fun fact: it's christmas merry christmas to everyone that sees this

It doesn't feel like Christmas today

The last dude getting up after all that, deserves an award even for doing that. He didn’t know where he was, but still he kept fighting. That’s mentally strong❤️

Jj’s shirt made me think i had the eyesight of a eighty year old

Yo how many people thought that they blurred JJ’s shirt

When ur so fast there’s no bots in the comments😁

You should react to "how far is tattoo far"

7:46 he sure did against Fournier

the window has been revelled and the room looks completely different hah

KSI finally opened the screen and revealed the window!!! Looks so different 😅

7:45 the only thing your giving is a crater in the canvas

JJ every time he sees something crazy: Eyo yo what's going on Me: Just having a laugh

10:44 Stan lee Chilling in the background (Middle right)

Damn why aren’t they the ones fighting. Also to the sidemen and viewers have a merry Christmas and a happy new year 🥳

3:29 the second loss shut got me hard

When Harry says “Come on Leon” at 11:28 then everyone just realised what he meant and the video just continues 😭😂😂

I don’t think the Sidemen realize that they’re making everyone’s day 10x better

Unpopular opinion:simon got a big forehead aswell

7:32 it's the royal rumble by now

ksi: i wouldve got on the top rope and give someone an elbow me: of course you would 😂😂😂

That thumbnail is such a big throwback when jj chugged a whole red bull playing cod black ops

I can imagine JJ flexing his 5 Diamond button when this channel hits 10M

Merry Christmas gents and all the Sidemen fans here🙌🏿🙌🏿🙌🏿

Josh: Give me odds on you going for the ref after one punch Jj: 12 *T W E L V E*

Sidmen just make my day thank you lads we are grateful

Who is here after KSI banged it with his Domain video???❤

KSI : You cant beat me Logan Paul : I know , but he can *Refferee introduces himself*

Ayo that thumbnail looks nostalgic af

Am I the only one who looked at JJ’s shirt every time he was full screen to see if that was the actual shirt or editing

Last time I was this early Arsenal was playing in the Champions League.

Jj:you gave me another bandana for Christmas Also jj:I love it

Anyone else notice Harry's Milkybar calendar 🥺

This is nothing when compared to when my Mom loses her cool...

The importance of me in my family is just same as Harry's in this video

Genuinely confused that I can’t find any “wHo ElSe Is HeRe In 2021” comments 🤣🤣🤣

JJ's room with the window open looks different 😂

You guys make my day every day I laugh every time I watch sidemen

Harry and JJ makes the reaction even funnier

That one referee who threw that guy to the ground and then challenged him to fight is a beast

Sidemen Reacts is growing at a mad rate and if you guys continue this way it might reach 10M before the 2nd channel

JJ's elbow comment did not age well

lmao imagine being a pro fighter and the ref beats ur ass with no difficulty like daymn when are there gonna be ref vs ref

I saw this video yesterday 😂 I'm glad they reacted to this video.

All the dislikes are from the referees in the video

Literally I’ve been watching all of them for years

anybody else notice JJs laugh at 7:50 it sounded like the mario theme

0:30 I like how Simon looks to his right on the webcam and that’s we’re jj is

Fun fact: People can suffer from a psychological disorder called Boanthropy that makes them believe they are a cow. SDMN Moo off?

Merry Christmas guys and gals have a wonderful rest of your day and an even better new year!!! Stay safe

Their reactions are priceless. KSI's always makes my day

11:07 when you both have he same favorite character in mortal kombat

Will be updating for the first 100 videos, 85 so far The number of times each sidemen have appeared in sidemen reacts: JJ: 45 Tobi: 43 Ethan: 43 Josh: 41 Harry: 41 Simon: 40 Vikkstar: 33 Number of videos: 85

Love to see Harry rocking the childish hoodie glad to have gotten one myself

Big up yourselves gents, top notch content keep it up, loving it 👌🏾👌🏾🙏🏾🔥🔥🔥🔥🔥🔥

First time I’ve seen KSI’s window open lmao 😂

Remember they used to post every second day Now they post everyday and I LOVE IT

4:08 As a boom mic operator that guy's technique was giving me the ANXIETY GEEEEEZ

This is the best group hands down

I hope jj sees this but i just found out that he aint gettin no money from utube and hes only making videos just for us big up man❤❤❤

Merry Christmas 🎄

First time seeing a window in JJ's room, mate. Dayuuum

KSI Is Amazing To Watch EveryTime I Am A Huge Fan Of KSI Always Will Be Forever

No One: what JJ says at least once every 3 videos: *"iTs 2020 mAn"*

JJ releasing the music video for Domain was one of the best Christmas presents ever. ❤

That last ref is a genuine guy, didn’t start throwing punches or get mad.

Refs got the most lethal rear naked choke, I’ve never seen anyone escape it from a ref

Nice! My Day is saved..

An elbow hm 😂

bro really gave elbow in future

The last one was so wholesome

Merry Christmas everyone ❤️🌲

Christmas joke of the day: Wife: I regret getting you that blender for Christmas. Me: *Sipping toast* "Why?"

10:43 that yeet was amazingly timed

Gotta love the milkybar calendar!

Can we appreciate the fact there uploading every day on this channel

As someone who worked as a referee for my local U13 and under league when I was in middle and high school, there was only ever one time I lost my cool. One match there was a parent who was drunk and being incredibly disruptive (keep in mind, this game was happening on a Saturday morning and the man was drunk). The man was constantly screaming, swearing, yelling insults and expletives at the opposing team and even threatening the parents of the kids on the other team. I had told him multiple times to quiet down and stop swearing in front of the children but he refused. It eventually got to the point where I lost my cool, dragged this man aside who was easily a foot and a half taller than me, started dressing him down with my best authoritative voice that I got from being an SPL in boy scouts and told him to get the fuck off my field and if he didn't I would be calling the police as well as contacting the league to get him banned from every field in the city. He left after that and I personally never saw him again at one of my games.

Truly disgusting, that some “people” would do this horrible thing.

these three guys crack me up

Lmao I literally got the exact same video recommended to me , 5 min before this video was posted

What a throwback using old KSI in the thumbnail

Mad respect to the refs who helped subdue the confused boxers. As a boxer myself, id feel terrible if I ended up accidentally throwing hands with the referee. Send that man a fruit basket or something lmfao

Who else imagining JJ diving off from The Top Rope giving a crowd of people a Elbow Drop lol

Am I the only one who saw JJ's t-shirt?

"That kick... So bad." Simon looks like he knows literally nothing about martial arts lmao
