Yes, because you haven't heard it labeled. Not being labeled does not mean it didn't exist.then, where does it come from?
I understand it’s always been the brown paper bag test going back for centuries & we pretty much all know that there was a brilliant movie done by Spike Lee in the 80s called school dayz about skin complexion. My point is I never heard black American women use these isms as an excuse till 2010’s
The fact that Spike Lee did a movie in the 80s after growing up in 60s Brooklyn means it existed during and before his time.
