I've heard Caribbeans say coolie. But if someone is known to be Black and not Caribbean and they go throwing that word around it could be a problem.You've lived in Brooklyn for decades and never heard a black person regardless of ethnic background use the word "coolie?"
When I was in college black American kids said sak pase, bredren, mida cono, and other cultural shyt all the time and no one was bothered with all this ridiculous "tHiS bElOnzgs 2 Us" politics. And American, Caribbean, and African brehs got together and said niccuh all day. What Brooklyn did you live in?
Some of yall live in a sad lonely world where this is the shyt you wanna worry about just to feel important, significant, and political. Black people aren't as needlessly tribal as you so badly wanna believe, and we shouldn't be. We exchange words, terms, phrases, and culture all the time. Grow up.
And ask yourself what's the difference between words like sak pase and bredren on the one hand and the N word on the other. The answer should suggest why that's a bad comparison.
As for people from different regions in NYC getting together and using the N word, *some* New York ADOS people are notorious for letting all types of people use the N word. People have long criticized alot of New Yorkers for letting Latinos use it. When I first got here I would hear Russian teenagers use it amongst themselves and I would pass by them on the street in Brooklyn. I think because NYC is a melting pot or salad bowl or whatever alot of people here have always felt entitled to unapologetically appropriate ADOS culture. And the ADOS people here sometimes let them because we're kind of outnumbered, at least among other African-descended people.
Bottom line, like I said before, I can't stop none of y'all from being corny and doing stuff like this, but that doesn't make it any less corny.
