Cunt. The words "see you" correspond to the letters "C" and "U" and the "next Tuesday" implies the "nt." This is one way to describe a person as a cunt when in polite company. Origin in Athens, GA.
"I was having lunch with the mayor and his wife yesterday, and, though he was perfectly agreeable, she was a see-you-next-Tuesday." "After our fourth date I realized she had a thing or two wrong with her see-you-next-Tuesday."
