Lorelai: She's insulting you!
Luke: No, she's not. Your mom's being great.
Lorelai: What? Were you in the room? Did you not hear the awful things she said?

Lorelai: "Rustic diner"? Rustic?
Luke: So?
Lorelai: Backhand slang for crap pile.
Luke: Or she was admiring its vintage feel.
Lorelai: Oh, what was the other word she used?
Luke: Charming?
Lorelai: Ah, slang for doggie poopy.
