Put it at the end of a short gag as the mock payoff, then follow it with Bruh for the deadpan reaction and Emotional Damage when the joke turns on the person celebrating.
About this sound
This is a 0.1-second trumpet blip from the Domer meme, a single tiny brass burst with no words or build-up. It lands as a quick, silly fanfare that feels deliberately overblown for such a short sound, then stops before it can become a proper tune. That contrast gives it an awkward, comic punch, like a celebration cut short at the exact moment it starts.
