Put it at the end of a failed escape or a bad excuse, then follow with awkward crickets while everyone stares, and finish with a chipmunk laugh once the embarrassment breaks. Keep it as the single beat in a short edit so the next joke still lands.

This is an extended flatulence effect built around one deliberately over-the-top blast that lasts nearly eight seconds. The drawn-out noise turns a familiar bodily sound into something cartoonishly toxic, as if a whole room has suddenly become unbearable. It feels crude, embarrassing and funny at once, landing as instant revulsion rather than a quick gag.
