Slim Who?
DJ Jake says:

     "Slim Anus is a name that was created by the music group, the Insane Clown Posse, to make fun of the rapper "Slim Shady". Slim Shady is more commonly known as Eminem. But to the Juggalos (followers of the Dark Carnival and of ICP), Eminem is commonly referred to as "Slim Anus" or "Feminem". Either name is appropriate. Before he was famous, he bandwagoned ICP, but since he was taken under the wing of Dr. Dre, he lashed out and dissed ICP at his concerts. ICP and fellow Psychopathic group, Twiztid, remixed Eminem's song "My Name Is" into a new song called "Slim Anus". This song was remixed so that it portrayed Eminem as a faggot. Eminem got pissed off and pissed his pants. Eminem's next album saw 2 more ICP disses, which ICP responded to with "Nuttin' But A Bitch Thang", which told the absolute truth about the BITCH Eminem. Since then Eminem's still the fake ass bitch he always was."
     "My name is DJ Jake, and I bring to you the #1 website that disses Eminem. I'm a down Juggalo for life, and NOTHING will change that. So when Eminem disses ICP, my devotion to the Psychopathic family made me create the Eminem diss song "The Really Slim Penis". In 2001 I began work on this website, either found at www.slimanus.com or www.feminem.com. Since then it has created mad controversy as Eminem fans from round the world discover that Eminem is nuthin' but a BITCH! Now it is time for you to discover that Feminem is just a little bitch claimin' to be some big tough guy, when in actuality he's a scrawny scared faggot. The only reason his albums sell so much is because there's a LOT of stupid ass people out there that don't know any better. Eminem fans are the stupidest people on earth! Enjoy this site!"
