When a girl has been in a bar too long and her vagina starts to gush with sweat and smell like stale beer
"I think I've been in this bar too long, my vagina is so sweaty. I must have a case of Bar Fanny! What if a guy wants to go down on me!?"

"Dear lord, that girl last night must have had serious Bar Fanny, it absolutely stunk and tasted like the end of an old pint!"
