Get the Stank Butt mug.
After having anal sex, the stink from the girl's ass that remains on your weiner. I've found that scrubbing with a brillo pad is the best way to remove said stink.

Get the Butt Stank on The Hangdown mug.
The humid poopy butt stank aroma forced through a fat girls ass crack when she sits down to fast and causes a pungent wind drift that smells of a sweaty, poopy and dirty pubic hair stench that gives males a hard on because it reminds them of butt fucking a fat girl on a hot and humid summer night
Tanya's muddy butt stank filled my nostrils like rotten cake batter that made me throw up in my mouth a little bit right after I tounge punched her fart box that resembled a boiling mud hole that I saw at Yellowstone national park while on vacation this summer.
