Someone who is black and into actual emo music and it's sub-genres (emotive hardcore, hardcore punk, skramz and maybe indie or alternative like Sunny Day Real Estate and The Promise Ring). These people most likely know what they're talking about and won't label themselves "emo" because it's just a genre of music (and an insult when the term originally came about).

Most people think "emos" or what is actually emo pop punk (people who listen to emo pop punk / alternative rock / pop punk bands) like early My Chemical Romance, Paramore, Fall Out Boy and Panic! at the Disco are all privileged white kids and that seems to be the case, but you can have different races being apart of the subculture / sub-genre as well. It's just more popular in Western countries because that's where the genres originated.

Conscious hip-hop (Common, Talib Kweli), R&B, Wu-Tang Clan, and the Backpacker culture can all be considered black emo aka nerd rap. Purveyors of Black emo are African-American musicians who make music about for the bling, benzes and bitches, but to propoke thoughtful introspection on behalf of the listener about the state of the Black community. They are often Black Nationalists. Kanye West can marginally be put into this genre.
