Place it just before the reveal in an edit, then follow it with a Bell Ding for a clean payoff or a Dramatic Dun Dun Dun when the reveal turns serious. Use it once per clip, early in the sequence, so the next sound carries the reaction.
About this sound
Bing Bing Bing is a short electronic cue of three high, bright beeps played close together, each one clean and cartoonish like a game-show ping. It feels playful and mischievous, building a tiny beat of anticipation before a reveal, a joke or an embarrassing reaction. The sound makes a simple moment feel sharper, as if it is nudging the listener to look closely at what happens next.
