The laugh comes from Team Fortress 2, the class-based shooter released by Valve in 2007, where the Heavy is the large Russian mercenary voiced by Gary Schwartz. His voice lines were recorded as in-game taunts and responses, and players quickly clipped the longest laugh for use outside the game. It spread through YouTube poops, Garry's Mod videos and gaming montages in the late 2000s and 2010s, becoming a shorthand for gloating. It remains popular because the performance is so distinctive that even people who never played recognise the character from the laugh alone.
