Ratatoskr comes from Norse mythology, the squirrel who runs up and down the world tree Yggdrasil carrying insults between an eagle and a dragon. Modern games revived him as a comic, talkative side character, notably in God of War Ragnarok and as a playable god in Smite. That fast, cheeky personality made his laugh easy to isolate as a reaction clip. It spread through gaming edits, streams and soundboards where creators needed a short taunt for trickster moments, and it remains popular because few laughs sound so small, smug and instantly recognisable.
