Glep is a small, green, wide-eyed creature who recurs in Smiling Friends, the Adult Swim animated comedy about a company that tries to make people smile. Unlike the main characters, Glep rarely speaks English, instead delivering cheerful bursts of invented syllables that fans have quoted and remixed ever since the show found a large online audience. Clips of his lines spread through short-form edits, reaction videos and soundboards, where the pure nonsense makes him instantly recognisable even to viewers who have never seen a full episode.
