This beef with Eminem and the Insane Clown Posse (ICP), goes way back to 1995. ICP consists of two people, Violent J (Joseph Bruce), and Shaggy 2 Dope (Joseph Ulster). Everything started in 1995, when Eminem was handing out flyers for a party he was playing at. The flyer apparently said "Appearance from ICP...maybe". Violent J wasn't too happy about this and he told Eminem to "fuck off" and that he wouldn't play at his party.

All this bull shit apparently hurt Eminem's pride, and so he started to diss ICP. He told people that he threw ICP out of a club in Detroit and he told a close friend that ICP were pussies for not responding. The club incident is true though, Eminem and D-12 chased ICP out of a club and then shot ICP's van with a paintball gun. This is briefly mentioned in "Nothing But A Bitch Thang" when ICP denies it: "you ain't never chased us out of no club bitch... only club you ever chased anybody out of was a gay bar bitch."

Eminem has dissed ICP on many tracks before. For example, on "Get U Mad", he says "dress up like ICP and have them come see you perform live" and on "Drastic Measures" he says, "ICP are over rated and hated because of their false identities".

Within the past few years, ICP has recruited Detroit rap group Twiztid to the fold and this Detroit crew released their first diss towards Slim with the infamous "Slim Anus"

Eminem was arrested a couple of years ago when he apparently saw his wife at the time, Kim, kiss an associate of ICP outside a club, and Eminem was arrested and given two years probation for having a concealed weapon.  The skit, 'The Kiss' on The Eminem Show is based around this incident.
