When one loses a cellular phone at a party, one must do something to communicate with the outside world. (To tell of how drunk one is) They instead decide to use Facebook to make these regrettable choices.
"heu suizy i kmwo i habe a girlfirne but i wnwnaa bang youj!"
The act of posting updates on facebook while drunk that one would not post when sober. Similar to drunk texting but out there for the whole world to see.
