Basically a man who wants to be with a female, but can't because she's in a relationship already so all he can do is just flirt, talk and do sexual things with her on the low.
I want her but her she's still in love with her boyfriend so I have to be her sidenigga.
The opposite of a niglet, it's a huge black man. Whether that means he's fat as hell or seven feet tall, it doesn't matter. Any definition of 'huge" willfit.
