When a man has anal sex with a woman who has diarrhoea.

Optional: After he has ejaculated, he then lies down while she sprays the contents of her ass all over his face.

Advanced: During the intercourse part of this, the man shouts "TIMMAY!! TIMMAY!!!" while thrusting.

Get the Dirty Timmy time mug.
A dirty old bitch with a penchant for sucking crooked penises and getting ass-fucked by door knobs and broom sticks while getting repeatedly teabagged by low-hanging old man balls.
My friend Robb is the biggest D.O.B.T. (Dirty Old Bitch Timmy) on the planet. He sucks more cock than all the whores in Las Vegas combined. His eyes are black and blue from all the old man nuts slapping his face and his hole is stretched wider than the Grand Canyon from riding so many door knobs.
