Get a Room!

J.D.: Hey, is it still funny to yell "get a room"? I don't care, I'm going for it. [yells] Get a room!

—Scrubs

Bender: Get a room, you two!
Man: We are in a room.
Bender: Then lose some weight.

—Futurama

Stock Response to two characters acting in an unusually lovey-dovey way, or flirting (but generally what each character thinks of as covertly, since they often Cannot Spit It Out). Occasionally used sincerely in the event of Coitus Uninterruptus, and in the other direction, also used on non-sexual friends (often but not always Heterosexual Life Partners) by the resident Deadpan Snarker. Mood Dissonance, both to "get back to the comedy already!" in the first two versions and to keep viewers from becoming more titillated than they should be for the time slot.

No real life examples, please; This is All The Tropes, not Tropes After Dark

Examples of Get a Room! include:
