The lame assumption that when you drink heavily, it would be an incredibly good idea to start calling people on your cell, because you're in such a stupor that you can't fathom them having anything better to do at 4 am than talk to your stupid, emotional ass.
Jane: I've had three Long Islands in an hour. I should probably call John. I haven't talked to him in so long! (dials John's number)
John: You dumb cunt. Leave me the fuck alone.
See drunk dial, but refers primarily to using facebook.com or other social networking sites (like myspace.com) to send your inebriated and often absurd messages. Generally only used if drunk dialing is not an option (i.e., the person you are drunk facebooking would not willingly give you their cell phone number).
Jane: So I went home with this guy after I met him at a party right? But then the next morning he wouldn't give me his number even though I was soooo in love with him. So like that night I got wasted with my friends and drunk facebooked him!
John: You're a crazy bitch.
