Meepo is a playable hero in Dota 2, the multiplayer game by Valve released in 2013, known for controlling multiple identical clones at once. His voice lines, including laughs, are triggered in game during movement, attacks and taunts, and players began clipping them for soundboards and videos. The laugh spread through Dota montages, streams and meme edits where a short character giggle was needed. It remains popular because it is instantly tied to Meepo's tricky playstyle, while also working outside the game as a generic mischievous reaction for jokes and lighthearted clips online today.
