I was also born a bit too late but I was active on IRC during the last 3 years of the 90s and remember the term script kiddie being so much a part of the fabric of IRC that we had already started to type around it, so to speak.
For example instead of saying script kiddies I'd just call myself a kid and it would be implied. Sort of like self-defamation to humble myself before older irc cats.
The beauty of irc to me was in part its whimsical nature. Making up words was something that happened almost every day and no one batted an eye.
Also trolling was part of this whole scene and no one cared. Everyone knew how to handle trolls and if you didn't you were part of todays entertainment.
Today it's all bullying and people are going insane over trolling but back then it was just part of the game.
IRC was truly where culture existed in my opinion. After newsgroups and such, IRC was live. It happened every day, all day. And night. In that sense it would be a much better source for slang terms than zines.
