Trollface is a cartoon face drawn in the distinctive style of rage comics, featuring a smug smile and mischievous expression. The drawing style is intentionally crude, but the expression perfectly conveys the satisfaction of successfully pranking or tricking someone. The face became the visual representation of internet trolling culture. The character's strength lies in its simplicity and the universal recognition of the smug expression. Even people unfamiliar with meme culture often understand what Trollface represents through the expression alone.

Trollface emerged during the golden age of rage comics on 4chan, a format where users created simple, crude comic strips using stock expressions and characters. The particular expression of Trollface, smug, satisfied, mischievous, became the ultimate punchline image for comics involving pranks, deceiving others, or revealing hidden jokes. The character became so iconic that it transcended its original context to represent internet trolling culture broadly. Trollface appeared in numerous memes, comics, and the internet references throughout the 2010s.

Use Trollface as the punchline image in comics or reaction images involving pranks, deception, or successfully trolling someone. The expression works for any situation where someone has been tricked or where mischievous satisfaction is appropriate.
