"White Trash" is a very funny expression to me, because it's the only racial expression you can use and no one gets offended. Nobody gives a shit when you say "white trash." Nobody gets all quiet like "Hey man, why are you talking like that?! That's not cool!" Nobody defends white trash. You could be talking to the most liberal hippy in the world and you go "Hey, I saw this guy, he was white trash." and he'll go "HA HA FUCK THAT GUY! White trash piece of shit. Let's laugh at him because he's poor and he's starving to death! Fucking loser! He lives in a trailer because he can't afford a house! Let's go shit right in his face right now!"
That's why they're funny too us, 'cuz they're fucking poor. "He wears stupid clothes!" BECAUSE THEY'RE FUCKING FREE, SO HE CAN EAT. HA FUCKIN' HA.
