B. Sweaty
A sweaty butt is when your ass is so damp it could probably start a fire. It happens when you walk around like a hot dog in a sauna or when you wear grey sweat pants and do squats until you’re a sweaty disaster.
I walked through the mall in July and my butt is now a waterfall.
My sweat pants are so soaked I could use them as a sponge.
I did 100 squats and now my ass is a swamp.
