Internet douchebag that whines and moans about everything you do on comment boards, chat rooms or bulletin boards. Biased and angry because of envious or unreasonable emotions these trolls will degrade you for even speaking or making any statement at all. Chat trolls usually fight in groups because of cowardice and because they are afraid of your intelligence and strength. Trolls usually attack or pounce on users for silly reasons and excuses most notably grammar or punctuation even though they can't spell worth a shit.

Internet Troll: Why don't you jump off a bridge and die, you cry baby go cry.
You: But I...
Internet Troll: Your so stupid why cant you even use the proper grammmar.
