[Scene: Monica and Rachel's, everyone is mopping around and eating ice cream.]
Rachel: Remember when we went to Central Park and rented boats?.. That was fun.
Ross: Yeah. He could row like a Viking .
Monica: (entering) Hi.
Ross: So how'd it go?
Monica: Oh, y'know..
Phoebe: Did he mention us?
Monica: He said he's really gonna miss you guys. (dubious look)
Ross: You had a rough day, huh.. c'mere. (She sits down and Ross strokes her forehead.)
Chandler: ...That's it. I'm getting cigarettes.
All: No no no!
Chandler: (leaving) I don't care, I don't care! Game's over! I'm weak! I've gotta smoke! I've gotta have the smoke !(this is the writer:Mon just broke with Alen who all her friends liked pretty much, and it was Alen who successfully get Chandler to quit smoking)
Its informal language for the fact he needs to smoke a cigarette. I remember this episode. Chandler was being pressured to give up smoking and he was about to give in and then Phoebe offers him 6000 dollars not to smoke :)
