drunkfriending 

The practice of, while intoxicated, friending people on facebook that you don't know, barely know, or who actively hate you. This usually leads to embarassment the following day when the friend request is rejected, goes unanswered, or results in a hostile message back but no friend confirmation.

"After I got home from the bar last night, I drunkfriended Kyle. I totally forgot about it until this morning when I got a message from him and all it said was 'LOL'."

"Marla, you really need to stop drunkfriending people. You're just embarassing yourself."
