a denny wink
A white guy who thinks he's black but still can't tell the difference between your cousin and the guy who got kicked out of the store and still uses the wrong shampoo.
He said, "I'm not white, I'm a denny wink. Your cousin is the real deal."
He tried to flex but spilled his shampoo and said, "This is what a denny wink does."
He said, "I'm not white, I'm a denny wink. I just need the right shampoo."
