The line comes from Dota 2, where Kunkka is a playable pirate admiral hero with a large set of recorded voice lines for combat, movement and denies. This short laugh is one of his deny responses, the kind of line players hear repeatedly during matches, which helped it stick in memory. Clips of it later circulated in Dota 2 montages, streams and meme edits, where creators used it as a quick taunt after a kill or a stolen objective. Its staying power comes from that clear, theatrical delivery, which works even without any game footage around it.
