San Ysidro Sanches 

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.

Damn, johnny's mom has been workin the fence all weekend and only gave one San Ysidro sanches
