When poop explodes from your ass like a nuke on Hiroshima.
1. "Dude, did you just nuke that bathroom?!"
"Yep. I made a poopsplosion."
2. "If we don't pull over to the nearest rest stop in the next two minutes.. Oh god.. I'm gonna have the poopsplosion of the century. Jesus, I'm sorry for eating all them bean burritos last night.."
When your kid has a diaper malfunction!
Oh, crap, gotta go, Conor is having a poopsplosion.
Oh snap, it spread to the inside of the baby carrier. Great, it is on my shirt. Awesome... it smells.
