A Johny Poo-Poo Incident
This is when you let out a turbo-charged dump so strong it rips your pants, you have to walk like a crab to the toilet, then throw your underpants out the window like it's a trash can.
I had a Johny Poo-Poo Incident during math class and had to go to the bathroom in the middle of a test.
My pants exploded during a Zoom call, and my boss saw everything.
I dropped my underpants out the window and my neighbor yelled at me.
