talking to someone, when all of a sudden you bust out a poopy in your pants situation
"hahahaha, I just laughed so hard I made a gigglepoop!!"
A foolish word to describe the act of defecating and/or breaking wind in your trousers as a result from laughing unexpectedly. It usually happens when you're most vulnerable and gassy.
"The other day I was sitting on my couch when Sean finished his joke, it made me gigglepoop."
