Place it at the very end of a short edit as the closing reaction, after the visual gag has landed. Follow an earlier bruh moment with this one for escalation, or precede it with a game show buzzer when a wrong answer needs a two step takedown.
About this sound
This is a short, three-second meme reaction clip built around the ROFL idea of rolling on the floor laughing, with no identified speaker or source production. It feels sarcastic and playful rather than genuinely joyful, turning a ridiculous moment into a quick cue that the audience is meant to laugh at it, not with it.
