A troll, most commonly encountered on the internet, is any person who purposely causes controversy in a web community and disrupts shit for his own amusement. Trolls have been referred to in the web community as, trollers, assholes, jerks, and scum of the earth douchebags. The term probably derives from "trolling" or "trawling", a style of fishing which involves trailing bait through a likely spot hoping for a bite. Troll is fine as a verb since trawling/trolling for comments and flames is innate troll behavior. Trolling is not to be confused with the gay slang verb "to troll", which means to trawl for anal sex, unless of course it's done by Perverted Justice.
