Mariah Carey's husband releases a diss track one year after Shady drops "The Warning."

A little over a year after Eminem released the scathing diss track "The Warning" aimed at Mariah Carey, Nick Cannon has responded with a diss of his own.

Cannon, who is Carey's husband, dropped "I'ma Slick Rick" yesterday (September 12). Over the beat of Cali Swag District's "Teach Me How To Dougie," Cannon borrows Slick Rick's cadence, delivery and flow. The song parlays lyrics from such Slick Rick staples as "Children's Story" and "La Di Da Di."

Only the second verse of the song, which clocks in at under three minutes, is directly aimed at Shady. "I dunno if I should hit him cuz he's feminine, Slick / Excuse me, Eminem, but why you lyin' on your dick? / Erectile dysfunction, you want to get a lump, then? ... / I see your mouth moving, but you're soft, Teddy Ruxpin"

In the song, Cannon claims that Eminem was afraid to confront him at the BET Awards, where he claims Shady was surrounded by security, whereas he was "rollin' dolo." Also notable is Cannon's use of the N-word, as the rapper has generally maintained a clean-cut image.

Last year, Cannon responded to Eminem's attacks on his wife via his blog. However, the post has since been taken down.
