Place it at the very end of a prank edit, after the reveal shot, then follow a beat later with the bruh meme button for the victim's side, or close the sequence with clapping when the trick actually worked on everyone watching.
About this sound
A short 2.8-second voice clip delivers the line 'You Just Got Luigi'd!' as a cheerful taunt, with the whole joke carried in that single announcement. It feels playful and smug rather than mean, like a victory lap after outsmarting someone, and it leaves the listener in on the gag even when they are the target of it.
