peeing out of my butt
Extremely loose stool consisting mostly of brown liquid rather than solid turds. Severe diarhea, the runs, the squirts.
The day after a delicious basket of spicy hot wings from Bdubs I was wishing I had a cold river to shit in. I had the shits so bad I felt like I was peeing out of my butt.
Pee out my butt
Shitting straight liquid. Usually alcohol induced.
Fuck I I gotta pee out my butt! I shouldn't have drinkin' all that High Life.
