when you get on Facebook so early in the morning and change your status (etc) and don't remember it later on in the day
Person 1: Wait, I don't remember putting this status up here...

Person 2: Were you sleep-facebooking again??

Get the sleep-facebooking mug.
When your Facebook status message says "is sleeping."
If Amy's Facebook status says, "Amy is sleeping," Amy must have been sleep-facebooking.
