A blood diamond is a Gruffnugget pulled from the ass of a black man. However this gruffnugget will also usually include a small portion of blood to it, thus dubbed a 'Blood Diamond'.
Slang for African American. Covert way for people to comment on black people between themselves or in a public situation without getting the shit kicked out of them. Can also add "shining bright" to the use of this slang to indicate alot of blood diamonds in one place, a take off from Rihannas song "diamonds"
