sangre sucia
Originally a term from the Harry Potter movies (referring to a Mudblood), this is used as slang within the metal music subculture to disparage people who listen to reggaeton.
This place is full of nothing but sangre sucia, let's go. / Don't hang out with this sangre sucia, you are ruining our image. / Those sangre sucia are gross, look at what they listen to.
