The phrase comes from Tag Team's 1993 single Whoomp! (There It Is), a high-energy hip-hop party track that quickly became a sports-arena and celebration anthem in the United States. Its call-and-response hook was easy to shout along with, so it stuck in stadiums, locker rooms, and party playlists long after its chart run. As short-form video grew, the chant was clipped into a one-second hype cue, perfect for reveals and wins, and it now circulates as a familiar shorthand for a moment finally arriving.
