A racial slur used to insult South Americans. The origin of the word derives from the fact that in poor South American countries, some people can be found living in garbage dumps living off the garbage or "dirt".
Mike: Damn dude, how can those people live in that shit?

Ron: Just ignore them dude, they're just a bunch of filthy, fuck faced Dirt Lickers.
