Spacey Defense 

When you get called out for committing a crime, and in response, proclaim that you're gay.

It comes from when Kevin Spacey was accused by Anthony Rapp of trying to molest him when he was 14, and Kevin Spacey responded by saying he's gay.

The Spacey Defense:

Everyone: Did you molest that 14 year old boy?
Kevin Spacey: I'm gay

The Kevin Spacey defense 

When you get called on doing something illegal or deplorable and come out as gay to deflect blame.

I hear that crazy guy that killed a bunch of people used the Kevin Spacey defense. What a hero.

Kevin Spacey Defence 

An excuse to get out of a sticky situation by coming out as gay, and thus attempting to undermine the whole point of the allegation.

Guy 1: So I owe you some money after a game of poker. I don't remember this ever happening though and I deeply apologise, these allegations have made me address other aspects of my life and it is now that I choose to live my life as a gay man.
Guy 2: Dude don't use the Kevin Spacey Defence
