clit slapped

When a girl heavily flirts with a guy or leads him on, and then abruptly disappears or abandons him just before he makes his move to close the deal.

John (at a party): "Dude, this chick was all over me for like three hours. It was a slam dunk that I was gonna bang her, but then she goes to the bathroom and leaves the party with her girlfriend without saying a word to me."

Tim (John's friend at same party): "Dude, you just got fucking clit slapped big time."
