Crab Rave was released by Irish producer Noisestorm through Monstercat on 1 April 2018, originally as an April Fools release. Its official video showed computer generated crabs dancing on a tropical beach, and that footage quickly became a reaction meme online. People captioned the dancing crabs to celebrate something unpopular ending or disappearing, and the format spread across social media and gaming edits. The song's upbeat drop remains widely reused because the crabs and melody are recognised even without any caption.
