When a girl gets so turned on by a man or a woman, that her vagina begins overflowing with wetness. Then, her vagina churns the wetness, like churning milk into butter, until it turns into foam. That foam is froth. It's sticky, moist, and thick, and feels awesome when you rub it on your cock/cunt. Like the shit at the top of a cappuccino, or a root beer float.
Guy 1: On a scale of soy milk to root beer float, how frothy was she?
Guy 2: She was like a grande mochaccino.

Guy 1: Man, I sent that bitch a winkie face.
Guy 2: She must be so frothy right now. We're gonna be able to surf over to her on a sea of froth.

Guy 1: I went to a foam party last night.
Guy 2: Oh, word? Where did you go?
Guy 1: To Mary's frothy vajee.
