An asshole that has not been properly cleaned before anal sex. The asshole is still steaming with feces and other nastiness. Stank, smelly, and otherwise unpleasant.
After Mike took a dump he left shit all over the handle of the hammer after shoving it up his asshole.
Dude, she must have had a musty hole because when i pulled out my dick was brown
musty hole: define #2
an elder woman’s vagina. often saggy, stanky, and just plain old looking. like a war relic. in need of douching or some good quality soap or some shit.
Damn it Agnes, your damned musty hole is stinking up the place! Get yo’ self some neutrogena!
