maid bating

The act of masturbating in a hotel/motel room with the door unlocked while the housekeeping staff makes their rounds, in hopes that a maid will walk in and find you mid-jerk with your boner in your hand. Can also be spelled maid baiting.

Every time I go on a business trip, I like to go maid bating with the hotel staff wherever I'm staying. It never fails to get a big reaction.
