Phoebe: (Clears Throat) Rach, so, that guy there. Straight or gay?
Rachel: (They both look behind them.) Well, I'd have to say gay.
Phoebe: Yeah? Why?
Rachel: Well mainly because he's kissing that other guy.
Phoebe: Oh no not that guy there. That guy right there. (Pointing to an attractive man sitting at a table behind them.)
Rachel: Oh yeah he's too cute to be straight.
Phoebe: (A woman with large breasts walks in the door) Ohh knockers will help us figure it out. (She walks by and he checks her out.)
Rachel: All right, straight, and not subtle. (The man gets up and leaves.)
what does knocker mean?
Is it a vulgar slang for a woman's breast?
and, what does subtle mean here?
Reminds me of a conversation on the sitcom Roseanne:
"You know, I read that a psychologist said that men are so obssessed with women's breasts is because they represent comfort and nurturing. They stand for motherhood."
"Oh. So I guess that's why they call them 'hooters.'"
