When you sleep so much, that you stumble around when you get out of bed.

When you are up so late or get so little sleep that you have the same symptoms as if you had been out at a bar/party pounding down the drinks... headache, stomachache, hungry, everything is loud, etc.
Man, I was at that party last night and didn't have a drink ... but was out so late I'm sleep hungover!
