Slim Shady is the alter ego of Detroit rapper Eminem. Slim Shady is the evil and mischievous side of Eminem. He was created by Em when he and some guys got together to make a rap group with the 12 best rappers in Detroit. It was called D12, or the Dirty Dozen. Since there were supposed to be 12 people and they only had six, they all came up with alter egos so there would be 12 members and Slim Shady was born. Eminem often raps through the point of view of Slim. He was not created in Em's first album Infinite and did not appear in his 2010 album Recovery. In the Slim Shady LP Slim was a childish drug dealer, drug taker, immortal, murdering, raping scumbag. He made a lot of jokes and did a good bit of horrible mischeivious things. The tone was still joking though. In the Marshall Mathers LP he did more horrible stuff, including some material about rape and serial killing along with more gang, drug, and violent activity. He was less pronounced on the Eminem Show and Encore as Em mostly rapped about being Eminem, but Shady was mentioned. Slim met his darkest days on Relapse, where he became a psychotic rapist and serial killer for most songs, going into detail about raping and killing women in horrible ways and at times being a gay serial killer who kills and eats men and sometimes does things such as aborting babies. There was some Slim Shady content in the MMLP2, but he was less pronounced.

Get a Slim Shady mug for your brother James.
Eminem's alternate name....kinda, more like the "evil" side of Marshall. He blames Slim for everything that happens, with his family, and work, that happens that is bad. And in one of his most recent songs "When I'm Gone" he "kills" Slim.

The darker, more evil alter ego of the rapper Eminem. In his own words, "what's the difference between Eminem and Slim Shady? well, Eminem would 'fick' you, and Slim Shady would 'fick' you and your mother".

the alter ego of marshall mathers. Slim is the villainous version of eminem, and completes tasks that em would like to do.
