A "citizen" of LA or the surrounding vicinity that is cleary and flamboyantly mexican or spanish. Has no consideration that we have no idea what the hell they're saying when speaking to a common American.
Dude, i was walking by a construction site and there were a couple of LAliens and they were shouting at me with all their rolled "rrrr"s and their "ñ"s. I just walked away.
