Mel Gibson Defense 

Using alcoholism to cover one's mistakes, like blaming Jews for all the world's wars. You can pretty much say anything you want, as long as your drunk it doesn't count. You also get special treatment later because you have a problem.

Mel Gibson Defence 

When on uses the excuse of being an alcohlic to justify doing something incredibly stupid or unorthodox. The term was originally coined after Mel Gibson repeatedly used the excuse of being an alcoholic for doing stupid things; notably making the Passion of the Christ.
