I read a thing once which said black people use it as an act of defiance, or of reclamation, of gaining control of a word historically used for oppression and turning it on its head.
How true that is, I have no idea.
I think it works quite well going by the Wikipedia definition:
an obvious problem or risk no one wants to discuss,[2] or a condition of groupthink no one wants to challenge.[3]
Everyone is aware of the possibility of there not being a deal and yet nobody is willing to talk about it.
Or maybe...
