^I find that vaguely insulting
You should.
In Internet slang, a troll is a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the deliberate intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion, often for their own amusement.
A. Koala gets provoked of his own accord and calls whoever he wants a troll. It's a label with no weight behind it in regards to Fan, Lucarr, and Colonel.
It would make more sense for me to be called a troll, since I like to be an ass every now and then. And even then I don't go around making everyone despise me on purpose.
