The Manual Sanchez is a prank created with the computer geek
in mind. It consists of coming up behind someone concentrating on the screen, scratching your own butt crack
and wiping it on his/her upper lip hence creating a stink mustache
that he will have to carry around for a while. Usually reserved for the closest friends or the worst enemies.
I just wiped my shitty finger under Ramy's nose...we'll call this one the Manual Sanchez!
