It's like gaydar- only instead of alerting you to a person's homosexual proclivities- it alerts you to the fact that they are a total, unadulterated CUNT.

Person 1: "I can't believe she cheated on Mike with seven different guys, including his best friend, before jilting him at the alter. I mean, she always seemed so......nice."

Person1: "Oh yeah? You psychic? lol."
Person2: "No, i have cuntdar: I can clock a cunt within a five mile radius. No joke."
