The sound comes from StarCraft II: Wings of Liberty, released by Blizzard Entertainment in 2010 as the sequel to the 1998 real-time strategy classic. Terran Marines, the game's basic infantry, can activate Stimpack, an ability carried over from the original StarCraft that trades a small amount of health for faster movement and attack speed. Players spammed the ability in competitive matches, so its hiss and yell became instantly recognisable to RTS fans. It later spread to gaming videos and soundboards as shorthand for a sudden burst of speed and aggression.
