Whenever a non-black rapper is trying to come up in the rap game, you can bet that he (sometimes she) has employed the use of token black guys in at least one of his music videos.
What do I mean by token black guys? Token black guys are black guys who serve the specific purpose to legitimize the non-black rapper's raps. They do this by simply bumping their head to the music or at the very least lend their "black presence" by just standing there in the music video.
Obviously the subconscious message that the non-black rapper is trying to send out is "see that black guy over there? He's black and he approves of my music."
Haha. It's funny because it's true. Almost all non-black rappers are guilty of this crime!
The only non-black rappers that don't need token black guys in their music videos are probably Latino rappers, specifically Mexican or Chicano rappers from California. That's because they got their own hip hop style and are pretty confident about it and don't really need the black man's approval.
