The first rule of hipster fight club: Hipster fight club must know about hipster fight club before it’s cool.
Screenwriter Max Landis “gathered acquaintances, friends both casual and close, paired them randomly, put them in a void, and asked them to hit each other in the face,” according to his YouTube account.
That’s it, really. The result is a hilarious doubling of that viral "First Kiss" video that went around a while back. And, as Landis puts it, “No one was pressured, and everyone was hit as hard as THEY asked to be hit.” So that’s nice. And although we’re merely observing reactions from this video and in no way endorsing the behavior, it’s kind of cathartic to get hit in the face, right?
Haley Joel Osment seems to think so – that’s him around 1:48.
