A Johny Poo-Poo Incident
This is when you poop so much it feels like you’re hosting a poop party, you crawl to the toilet, and throw your underpants out the window like it's a concert.
I had a Johny Poo-Poo Incident during my science test and had to go to the bathroom three times.
I pooped so hard during a movie that the theater had to close.
I dropped my underpants out the window and my neighbor took a photo of it.
