when one consumes a large amount of alcohol, and proceeds to have sex with a member of the fairfield lacrosse team. Upon awaking, usually naked, the person has no recollection of the alleged sex, until another member of the lacrosse team informs them later in the day. Also, the person who is the lesser of the drunk is later referred to as blackout sex.
Blackout sex just walked by. She has no idea
