That one guy or girl in your group of friends who is either a klutz or just does things others don't. You can always rely on him/her to say the wrong thing at the worst moment and its funny as hell. Things tend to happen to this person that are so ridiculous and funny they would only happen to him/her and no one else on the planet. The way this person carries him/herself, the things he does, says or the actions he/she takes are so funny and meme-able that social media pages will begin to pop up, dedicated to meme and or play off of this person by posting outrageous and/or controversial things that this person would say or do. These "alternate" profiles will eventually lead to much more enjoyable and crazy content than the original friend could conjure up on his/her own.
Sitting on a crowded train:
Brosef: He braj have you ever gotten into a fist fight?
Braj: I don't know brosef, have you?
Dude: (Very Loud) Why wont you guys stop talking about fisting?
