A whole new level of blacking out. This word is reserved for those die hard alcoholics who party on the reg and pound shots on the reg.

Things that normally happen when you are blackedthefuckout: shattering your iphone, waking up the next morning in unknown territory, etc.
Jasmine: Where did Kayla go last night?
Tiffany: I don't know, she was blackedthefuckout
