Blackout is the term used to describe when a person is so drunk that they wake up the next morning with temporary amnesia, no recollection of what they did the night before. It can be used as a verb or as an adjective.
verb: "Oh man I blacked out so fast last night, and then I woke up in this ugly girl's room."

adj: "I was so blackout man, everyone was wasted."

A state of mental and physical impairment you enter after reaching a blood alcohol level of .20, which causes you to act in an uncontrollable manner. Unfortunately, the black out enables you to recall any of the events that occurred while acting so recklessly, and almost always guarantees awaking to wounds you do not remember getting or next to a person you do not remember sleeping with.
