Literally the stupidest thing to grace the Internet. Some attention starved asshole gets the bright idea to record his/her ugly face watching a YouTube vid or, god forbid, a 20-40 minute episode of something and expects us to sit there and watch them make facial expressions or some shit. It's literally watching a video of someone watching a video! Their face takes up 80% of the screen and the thing they're watching is usually miniature and in the corner. It's a pathetic fad that needs to die very very quickly. Newsflash people: NO ONE CARES WHAT FACIAL EXPRESSIONS YOU MAKE OR WHAT STUPID SOUNDS COME OUT OF YOUR MOUTH WHEN YOU WATCH SOMETHING!
Guy 1: Hey bro, have you seen this live reaction video of the new RWBY episode?
Guy 2: Uh, no, I'd rather watch the actual episode, not some guy's ugly face.

Get the reaction video mug.
an annoying cheap way of getting youtube views. often uses obnoxious, ridiculous, exaggerated thumbnails of the viewers face to draw attention. peak narcissism.
Dude, check out this reaction video to this song!

No thanks, who is this no-name loser anyway and why should I care about their worthless reaction?
