Shaggy Defense 

When someone is caught committing a crime (mainly one sexual in nature, but can refer to all crimes), with overwhelming evidence to prove they did it; in their defense, the culprit denies that they were the one caught doing the crime.

Derived from the Shaggy song "It Wasn't Me", which describes a man being caught having sex with another woman by his wife, and subsequently denying that it was him she actually saw.

When caught on video having sex with a 14 year old girl, R. Kelly employed the Shaggy Defense; he just denied that he was the one in the video.

The Shaggy Defence 

The defence favored by the protagonist in Shaggy's song "It Wasn't Me". Despite overwhelming evidence to the contrary, he maintains his innoncence by simply saying it was somebody else. Also liked by R. Kelly, O.J. Simpson, and Phil Specter

Person A: Oh, man, I just killed 2 dozen people. There were over 50 witnesses. My shirt was off and everyone saw my tattoo that says "My name is Jeffrey Dahmer". What should I do?
Person B: Say it wasn't you.
Person A: Oh, the Shaggy Defence...hadn't thought of that.
