I don't hate kids, personally. We were all kids once, and kids can be just as intelligent and as mature as adults; adults can be just as foolish and asinine as young children.
What I don't like is immature behavior and tons of chatspeak (and hideous spelling by native English speakers)--mainly ignorance and rudeness--no matter what age group the person belongs to.
"CN U GIV ME DIMOND PLZ????!!" <--This is begging, chatspeak, caps, misspelling and so on, and I just want to boot these people from my server outright (although I don't). The problem is, we don't have a word for this type of person, so people just say "kids."
We need a word to describe immature people who can't spell and don't know what "chat etiquette" is. Something not derogatory so it won't get censored, something to simply refer to that kind of person.
Maybe "Spaps." Spelling + caps = Spaps. Damn Spaps, get off my server. >.>
