Trollface is one of the most recognizable icons of internet culture, originating in 2008 on DeviantArt by user Whynne. Initially part of a MS Paint comic about 'trolling' on 4chan, the mischievous, grinning face quickly became the universal symbol for internet pranks and 'rage comics.' It is typically used to represent a character who has successfully provoked someone or to signify a deliberate act of annoyance. Over the years, Trollface has evolved from a simple comic panel into the 'Trollge' horror subgenre and remains a foundational pillar of meme history, embodying the spirit of early web mischief.
