The sound comes from Jason Derulo's habit of singing or saying his own name as a producer-style tag on his pop releases, a signature that became especially recognisable in the early 2010s. Because the tag is so short and distinctive, it spread beyond full songs into memes, soundboards and quick reaction edits. People still use it because a two-second clip instantly signals mainstream pop energy, confidence and a slightly exaggerated sense of drama without needing any longer setup.
