A robbery scam where a woman poses as a prostitute and lures the john/mark into a room. When they are in bed, the woman's male partner rushes in, usually brandishing a gun and posing as a jealous husband or jilted lover. The mark leaves in a hurry, without his clothes or valuables. The perpetrators, or "Murphy artists" collect their loot and escape.

A similar version was used in the movie Porky's as a prank involving a black guy with a machete, chasing the naked crew into the woods.
New Orleans used to be the capital of the Murphy scam.
