As with drunkspacing, this is the act of browsing facebook whilst drunk, adding randompeople, leaving unnecessary comments, and "tagging" all your cute friends in your new drunken pictures.
when someone is really drunk, and gets on facebook, and posts all kinds of random things that will soon be regrettable. its a bad habit to break. for some unknown reason, drunkbookers think that ALL of their friends should know they are drunk and what they are doing.
Dude, i got hammered last night and was drunkbooking. I had 5 different statuses telling everyone how drunk i was. I gotta quit doing that.
