The available details only identify this clip as a short “3, 2, 1, go go go” countdown, and no reliable original source is confirmed here. Sounds like this spread widely through meme edits, gaming videos and short-form posts because they create instant anticipation in just a few seconds. The format stays popular because it is easy to sync with a visual start point, whether that is a race, a jump, a challenge attempt or a sudden burst of action.
