Similar to a blackout (alcohol related amnesia), except the temporary amnesia is caused by vagina, rather than alcohol or drugs. The primary symptoms of a pinkout are poor judgment and bad decision making.
John: Dude, next thing I knew all her stuff was moved in to my apartment! I don't even remember saying ok to that! I must've been in a pinkout or something...

Passing out during sex. Usually caused by heavy drinking.
