Drinking
Why would anyone want to drink something that tastes awful, so they can have a night of fun they probably won't remember, and wake up feeling awful?
If I'm gonna have a fun night, I want to remember it, not hear about it from others. And the risks are too great. Risk of doing something stupid I would never normally consider that could embarrass, injure, or kill myself or others.
If that's your idea of fun, more power to you, but I'll pass.
