Oaschwossa
Oaschwossa is the smelly mix of pee and poop that leaks out when you sit too long and your butt feels like it's on fire.
My pants are soaked from Oaschwossa. I smell like a sewer.
I tried to hide my Oaschwossa in my backpack. It came out during lunch.
My mom called me into the bathroom. I had Oaschwossa oozing out like a volcano.
