I learn something new every day- Dirty Sanchez
Dirty Sanchez, a "moustache" made primarily of fecal matter, applied by the finger or penis of one's sexual partner.
It is performed by sticking one's finger (or other object) in one partner's rectum and then swiping a line of feces under the nose, making a "moustache."
The Dirty Sanchez is a popular turn of phrase, appearing in a variety of pop culture references including the name of a bar in the movie Dodgeball: A True Underdog Story. The bar's mascot was an apparently hispanic woman with a moustache. Another popular reference is in The Aristocrats joke. Also in The 40 Year Old Virgin, the character Mooj makes a reference to the Dirty Sanchez while talking to Andy.
EWWWWW!!!
