When a hoe blows mad mud and does not wipe, and you fuck the SHIT out of her asshole; followed by making a ring of shit around her asshole.
Yo, that bitch was hungry for a dirty tire. So she came out of the shitter and I slapped my dick in her dirty asshole and made a fat ring around her pooper. Wow, it was great.
To finger a girls and rub the shit around her asshole, or to give a dirty sanchez to her asshole
Instead of giving her a dirty sanchez give a Dirty Tire
