Team Fortress 2 is Valve's team-based multiplayer shooter released in 2007, and the Scout is its fast, cocky Boston runner class, known for quick taunts and boastful voice lines. Short clips of his laughter circulated through gameplay videos, YouTube edits and meme soundboards, where the exaggerated woo hoho yeah haha became shorthand for a sudden, smug celebration. It remains popular because the voice is instantly recognisable to players, even without any visuals, and the three-second burst fits neatly at the end of a joke, a kill or a winning moment.
