[cunt]stumped

When a woman's potential to get laid by a man is thwarted by her girlfriend.

Lindsay, on the verge of going home with John the supermodel for the evening, was suddenly cuntstumped by Simone her bitter, resentful, and inebriated best friend who claimed she lost her keys and needed a ride home.
