sean-ass 

An ass that bleeds for no known medical reason, also could be an ass that stinks like no fuckin other.
Can be treated, yet not cured, with any form of blockage (eg. toilet paper, tampon, or any other anus sized object.)

I have sean-ass after last night.
Dude I have sean-ass, I need a shower big time.
