The Trollface is very commonly used in the game, Minecraft, Fffuuu The Game, and Trollface Quest Series. Trollface is a comic character wearing a mischievous smile that is meant to represent the facial expression of an Internet troll.
Trollface is a meme associated with 4chan and other so-called "troll" sites. Normally it is little more than a mascot for trolls but there are many comics that show Trollface to be a living creature and he is symbolic of Internet trolls and the chan culture. Trollface is often shown to do incredibly stupid, evil or obnoxious things and delights in mischief.
