When you have to repress a fart and it kind of goes off inside you and you feel it bubble its way back up in out of sight before it escapes.
Imploding is a techincal word by a Georgie where a fart is repressed when youre in awkward situations like a que, a date or an interview, even in a swimming pool! All applies and we all implode. Dont do it for too many hours though or you might explode and die.
