Morning Crust 

The foul remnants of a drool-ridden sleep, or the substance located at the medial corner of the eye. Morning Crust can be found dotted around your lips, chin or cheeks after waking up from a good to excellent sleep or nap. Morning crust can also be discovered in the eyes, a small white build up of salt and water from your tear ducts can develop, thus leaving you with "Crusty eyes."

"Yo, Bill...you've got some mad Morning Crust in and around your mouth"
"Oh thanks John, you saved me some embarrassment, I hate Morning Crust"

Morning Crust 

When you spend all night buying pay-per-view pornos and rub the pope all night long. You eventually pass out and in the morning when you wake up your sheets are all crusty from your spooge.

Guy 1: Hey man what's going on?
Guy 2: Oh, you know, putting clean sheets on, dusting the mattress.
Guy 1: That's bullshit you spent all night jerkin it and now you have Morning Crust.
