Wasted yellow 

This is a term I’ve heard used when a light skinned female has strong Black features like big lips and nappy hair, or is just generally unattractive. It’s derogatory and means you’re ugly for a light skinned chick, as if being light skinned is synonymous with being beautiful.

That girl Tiny from Escape is wasted yellow with her funny lookin self.
