Spanish-language expression meaning:
a) Kitchen boy. The guys who clean up the Chef's mess and scrub the frying pans and carry stuff around. In this context it's still used in Spain.
b) In Mexico, it's an all-purpose insult enhancer, which would be roughly equivalent to the use of *fucking* in English. If Jay (Silent Bob's hetero life mate) spoke Spanish, he would say *pinche* A LOT.
Pinche is strongly associated with cursing in Mexican Spanish and the very moment you use it gives you away as a Mexican national. So you pinches gringos take that into account if youre trying to pass for an Argentine or whatever.
c) In Mexico, it's also used as an adjective to describe something as insignificant, lousy, miserable or worthless.
a) Se solicitan 2 pinches de cocina medio turno. (2 kitchen boys are needed for half shifts)
b) Pinche gringo culero ve a chingar a tu reputisima madre! (Fucking gringo asshole go fuck your loosecunt cocksucking mother!)
c) Tu pinche hermana está bien pinche, wey. (Your fucking sister is so fucking ugly, dude!)
