A lovely term, for which I've found the following definition:
SNERT... That's what they call the real trouble-makers of cyberspace.
Attributed by some to Kurt Vonnegut, the term stands for "snot-nosed
Eros-ridden teenager." It concisely captures much of what many cyberspace
deviants are all about. They thumb their impudent noses at authority figures
and smear their ooze of discontent all over themselves and others.
Frustrated drives seeking an outlet may fuel their misconduct - frustrated
aggressive drives as well as sexual ones. They often are adolescents. If
they aren't, then they are +regressed adults acting like adolescents+. In
some communities, the term "snert" broadens to include any acting out,
annoying, disruptive user.
