The sound comes from Team Fortress 2, Valve's team-based shooter released in 2007, where Heavy Weapons Guy is the slow, powerful class known for his deep voice and minigun. Players began clipping his exaggerated voice lines for jokes and animations, and the Pootis Pow laugh became a shorthand for triumphant, overconfident humour in gaming communities. It spread through YouTube edits, Source Filmmaker videos and soundboards, where short recognisable character clips are easy to reuse. It remains popular because the laugh is instantly readable even without context, turning a simple win into a joke.

Heavy's Pootis Pow Haha sound from Team Fortress 2 captures his booming Pow followed by a manic laugh, used in gaming edits and meme videos for comic kills.
This short clip captures Heavy from Team Fortress 2 delivering his famous Pootis Pow line before bursting into a loud, hearty laugh that lasts just under two seconds. The voice is deep and booming, with the sharp Pow landing like a punchline before the laughter stretches the joke out. It feels triumphant and a little unhinged at the same time, which is why it lands so well after a surprising kill, a failed plan or a moment of pure chaos. Listeners recognise the character's heavy accent and cartoonish confidence, making it nostalgic for longtime players and funny even for people who have never played the game.
