B. Sweaty
A sweaty butt is when your ass is so wet it could be mistaken for a puddle. You get it when you walk in the heat for too long or when you wear grey sweat pants and work out so hard you’re basically a human mop.
My butt is so sweaty I think I could drown in it.
I walked outside in 90 degree heat and now my pants are a second skin.
I did a workout and now my ass is a sweat lake.
