I wrestle with the use of this word...
There's nothing as endearing as being able to walk up to a black male you barely know and hitting him with the, "Was sup my nikka!" and exchanging dap.
It's a brotherhood that white PEOPLE WISH they could be a part of. They have everything else on this planet except free reign to use this word...and it kills them.
We've given away everything else, perhaps we shouldn't give this away?
It's a powerful thing, that can only be pulled off by a swagged out people as black americans, to take a negative term and make it cool. To take it from white people and make it ours!
We've done similar with other words, it's what we do!
