How bad is what this guy called me the other day?

He called me "pocha"... I don't speak much Spanish so he's right about that... But I'm Puerto Rican. I don't know. This has been bothering me since last Friday. I've never had "pocha" thrown at me, especially not from some white dude from Cali. I think he's just some white brodude who thinks all brownish Latina chicas are Mexican...
