It means that he still won't have sex with her.

Means he's a prude :P

"Put out" = provide sex (in return for dinner)... the joke here is the gender reversal: Phoebe is being the predatory one. In this case, "won't" has the meaning of "doesn't want to"/"refuses to". As a phrasal verb, "put out" can have several meanings. As well as the above example: Put outside = "I put out the cat last night." Displease = "He was put out when he realised he had to work this weekend."

Yep, Peachey's right .

You don't mean it has a litarary meaning, do you?:( It's not phrasal? Gosh! I'm embarrased.
