My friends and I starting in around 5th grade, were so sarcastic and corrosive, just acidic humor that we turned on each other, and anyone else that we happened to target. I got some, but I was never really "roasted" that much. I think it affects everyone differently. I think it become a part of most men's inability to emotionally connect, or be sincere with many things. I remember us just tearing into people in the most insulting and demeaning, horribly cruel and often hilarious ways.
This is kind of different, but I caught up with a childhood friend a few years ago, and we were talking about growing up, and I noted that he and my other boy were always fighting, and getting into it, and he said, yeah that was just us being competitive, and I think you never cared about any of that. That's kind of how I felt as got into my late teens (more accurately my 20's) about constantly putting people down. By the time I was like 30 I could probably articulate that.
Affection, friendship starts needing to be defined solely with jokes or with sarcasm, which is not to say you can't laugh at each other or yourselves, I do clown my friends, but it's with love, and not trying to enforce behavior or group norms. but I think many people carry those childhood habits FAR into adulthood and never learn to let it go, or ease up.
