Sometimes shortened to just "washed". Used when referring to you or another's energy level after a late night of partying or playing hard during the day. Usually in response to whether or not said person is ready to get that night's party started.
Dude.. I'm so washed up... those shots at 3am did me no good. I need a nap.
Man.. I'm washed. Too much hoops today. I need a red bull before I can kick it into high gear again.
