As far as I remember reading about it, "trolling" was a fishing term where you cast your line and it skips across the water "baiting" the fish.

An alleged troll is "baiting" another member to break a forum rule most likely the "no personal attack" rule. It is basically instigating arguments, sowing discord, creating hot topic threads with the intent of dividing a forum. When he is outed then he is a bona fide troll.
