Slark is a playable hero in Dota 2, a multiplayer online battle arena game by Valve, where he is known for slipping in and out of fights with stealth and speed. His distinctive laugh comes from his in-game voice lines, which players hear when he taunts opponents or escapes danger. Clips of the laugh spread through Dota highlight videos, streams and meme edits, where it became shorthand for a cheeky, outplayed moment. Because the sound is short and instantly tied to that trickster style, it remains a popular reaction sound for gaming content.
