Masturbating for the sole purpose of falling asleep. Used when you have to get a good night's sleep but you're not tired.
Guy 1: Dude I have to go to a job interview tommorrow morning, we shouldn't have chugged all those Red Bulls.

Guy 2: Don't worry. I brought a Playboy, just go sleep-off in the bathroom. You'll be drowzy in no time.

Guy 1: Thanks man.
