Sledging can be a very fun fantasy to imagine out in your mind about people you can't stand, and can be quite therapeutic. When somebody's really bothering you or you just can't stand somebody cause he's a big fag or she's a fuckin bitch, you can just close your eyes and imagine beatin the shit out of that person with a sledgehammer (in your mind of course, not in real life).
This is a safe way to release anger and come to terms with your disdain for other people.
