Friends Season 1 Episode 3

Ross: Hey. Oh, oh, how'd it go?
Phoebe: Um, not so good. He walked me to the subway and said "We should do this again!"
All: Oh. Ouch.
Rachel: What? He said "We should do it again," that's good, right?
Monica: Uh, no. Loosely translated "We should do this again" means "You will never see me naked."
Rachel: Since when?
Joey: Since always. It's like dating language. Ya know, like, "It's not you" means "It is you."
Chandler: Or "You're such a nice guy" means "I'm gonna be dating leather-wearing alcoholics and complaining about them to you."
Phoebe: Or, or, ya know, um, "I think we should see other people" means "Ha, ha, I already am."
