Context

This line is spoken by Hannibal Lecter, played by Anthony Hopkins, in the film The Silence of the Lambs, directed by Jonathan Demme (1991). 

Special Agent Clarice Starling (Jodie Foster) uses one serial killer to catch another in the thriller The Silence of Lambs. With the knowledge of Hannibal "The Cannibal" Lecter, she catches the cross-dressing, woman-skinning killer Buffalo Bill. There's one problem with her plan, though, and that's when Dr. Lecter gets away.

He calls Clarice to let her know that he won't go after her. He respects her too much to do that. Aww. Isn't that what every woman wants? The respect of a serial killer?

Then he lets her go, saying he's "having an old friend for dinner." The old friend is his nemesis, the head of the psychiatric prison that housed him.

But look out, buddy, because when Dr. Lecter is having you over for dinner, you're the dinner.

Where you've heard it

You've heard this if someone is inviting you over for dinner, and you're going to be the main course. Don't RSVP to <em>that </em>invitation.

Pretentious Factor

If you were to drop this quote at a dinner party, would you get an in-unison "awww" or would everyone roll their eyes and never invite you back? Here it is, on a scale of 1-10.

Unless you're actually planning on serving freshly sautéed human, you'll sound pretentious using this quote. And if you're faking it, you won't ever be Hannibal Lecter; you'll be Hannibal Lecter's dessert.
