Short countdown drops like this became a staple of edit culture because they give creators a ready made structure, three beats of anticipation and one clear impact point. The 3 2 1 Drop It phrasing follows classic DJ and dance track cues where a voice signals the beat to enter, and that format was widely copied in remixes, transitions and short form video edits. Its appeal is timing rather than a specific source, so it travels easily between gaming, fashion, comedy and reveal videos without needing context.
