When a guy is under the impression that the girl he is about to have sex with is white, and she spreads her legs showing her purple-tinted vagina, demonstrating that she is not white.
"So I took Alisha out for dinner last night, and we had sex?"
"How was she?"
"She had the purple surprise."
"How was she?"
"She had the purple surprise."
