Gingexican

A person of Mexican descent that is a ginger. Rarely seen in the wild, this species of Mexican is extremely rare, ugly and annoying. If you ever run into one, I advise you to leave immediately before you attract its attention.

Tim: Dude, what's that?
Jim: Oh Shit! It's a Gingexican!
Tim: Fuck dude, let's get the fuck out of here!
