In relation to a dirty sanchez, a person who appears somewhat unhygienic and presumably is going to start trouble.

The most badass Spanish teacher you'll ever meet. They call her Mrs.Sanchez but that is just a cover-up of her true identity. She is majestic, strong, cunning. She has the power to kick ass. She's so Spanish she'll speak Spanish in a French-speaking country. If you don't watch your back she'll shove a taco and/or a burrito up your ass. Never mess with the Sanch, she won't take it lightly. If you really wish to challenge her protect your upper lip from getting sanched. She has a beautiful wart on her nose and she has the legs of a schoolgirl. Her man face really brings out her eyes.

Similar to a dirty sanches, but it must occur in San Ysidro which is a prominent US/Mexico boarder crossing. A person in the US climbs the fence and takes a crap on the whore on the other side and then throws a few dollars down to the other side.
