Nudebook

To facebook in the nude, as in bare ass naked. This often happens after one gets out of the shower and decideds to check facebook before getting dressed. It can also happen any time of the day in which one decides to be naked while at one's computer.

"I was NUDEBOOKING in my room the other day when my friend Sarah walked in... then we got it on."
