P-Mud
When your guts are so confused they decide to poop and pee at the same time like they're best friends having a party in your bladder.
I was eating a whole pizza and suddenly my body was like, 'Why not? Let's do this.'
My dog just looked at me like I had betrayed him during a P-Mud.
I tried to hide it in the school bathroom but the toilet was already occupied by a kid who had the same problem.
