The sound comes from Tekken 3, Namco's landmark fighting game first released in arcades in 1997 and later on PlayStation. In the game, 'Chicken' is tied to a counter to reversal techniques, which is why the clip became shorthand for reading an opponent correctly. Over time it spread through combo videos, arcade nostalgia posts and meme edits that borrow classic fighting game audio. It still gets reused because the line is so short and instantly signals a clean counterplay moment.
