Caroluta
A type of prostitute originating from Catalonia, Spain. A Caroluta, usually female, pretends to be unaware that she is a woman of ill repute when questioned about it, yet all her friends really know what kind of shady lady she really is.
Man 1: Oh look at that respectable young woman originating from Catalonia over there. I think I'm going to try and get her number!

Man 2: No way Jose! She's a total Caroluta!
