so your fucking a bitch in the ass. and sinse she did not show you the curtacy of whiping good enough, you give her back whats hers by whiping it on her uper lip, which gives her a dirty mexican mustache

A British TV show that is wrong on so many levels

A Dirty Sanchez is a Sexual act that is usually performed by White people typically Trailer trash. It is when a couple of the same or opposite sex engage in anal sex and the one who is giving it to the other in the ass will either take either his shit covered Dick or finger and make a shit mustache then calling it a dirty Sanchez because from a Caucasian point of view it might resemble a thin wispy Hispanic mustache.

When a man (or woman) has a thin mustache on his or her lip. You may see many Mexicans with Dirty Sanchez's

when you have sex with a person and then you get some shit and smear it on their upper lip, looking like a moustache

Where a dude plugs up a girls(or dude, ain't gonna be rude) ass with his dick and takes it out, puts it on the upper lip(below nose) and leaves a shit-stash.

ALL OF YOU ARE WRONG!!! It's when a girl is on her period and a guy takes the tampon out with his teeth, then shakes it back and forth leaving two red stripes.
