Every college student's security. The state of perfect drunkenness in which all pole dancing, stripping, shot taking, and making out cannot be remembered. The state that helps you forget the night before.

When you've had so much to drink, you literally cannot function in a social situation. Sometimes victims possess the knowledge that they have indeed drank too much, sometimes the situation is known only by your peers. The words "Im so wasted" or " I shouldnt be here" frequent the victim. The next day, one will not remember anything that happened during the event.

When you get so wasted/faded that your brain stops storing conscious memory's, and anything that you do while blacked out will not be remembered tomorrow.
"blacking out is the action that leads to being blacked out."
Black outs can be very unsettling/dangerous, but also create potentially hilarious situations.
"Dude, Bob's blacking out."
"Why? What's he on?"
"He took a couple Ambiens and another three shots."

A black out (or blackout) is another word for a mass murder. A black out is when someone goes to someone's home to kill everybody there.
"Yo, my bitch is cheatin' on me with some other nigga!"
