look up any word, like sex:
All of you need to get your minds out of the gutter; that is disgusting. A dirty sanchez is simply when one sticks their finger into one's own butthole and then puts it into another person's ear, using a twisting motion similiar to that of a wet willy. So there!
After I gave my friend a dirty sanchez, I made sure to wash my hands well.

ok, a dirty sanchez is acutally when a guy has anal sex with a girl-or it can be a guy, whatever gets you going-and then after, the guys dick is sucked so that shit is on the upper lip of the sucker looking like a mexican mustache, the dirty sanchez
After tom and sheila had anal sex, she gave him head and got the hugest dirty sanchez above her lip.

an affectionate term, for an affectionate act. After a session of sweet loving, the male partner wipes his hand accross his backside, paying particular attention to the index finger. The finger is then wiped gently accross his female partners top lip, leaving an authentic looking mexican moustache.. Or a 'dirty sanchez'.
I love you more than anything, please accept this dirty sanchez as a token of my appreciation.

I. The man and woman (or man and man) engage in anal sex
II. The male continues by inserting his throbbing cock into the male/females mouth, hense leaving fecal matter in and around her/his mouth
III. Finally, they share a romantic kiss spreading the fecal matter from one partners mouth to the others
1. My girlfriend loves to eat shit so I gave her a dirty sanchez
