I call all my white friends "nigga" - but I've never called any of
my black friends nigga' - because of the reason you've posted.
You never know how a black man will take that so I just never
go there.
But, if you've known each other that long - I think he just feels
comfy enough with you to say it to you. He prolly says it to his
white friends too. So, I wouldn't take offence to it.
Big difference between "Nigga" and "******"
