This was released as the first single from Eminem's eighth album, The Marshall Mathers LP 2. The record is a follow-up to Eminem's Marshall Mathers LP, which was released in 2000. The Punk-Rap throwback was premiered on August 26, 2013 on Eminem's Sirius/XM radio station Shade 45.

The fiery Rick Rubin-produced track pays homage to old-school Hip-Hop and samples the guitar riff and vocal from Billy Squier's 1981 hit "The Stroke." Squier was previously flipped by Rubin when he borrowed the arena rocker's "The Big Beat" for Jay-Z's "99 Problems." The song also samples the "kick it" hook from the Beastie Boys' Licensed to Ill track, "The New Style." That tune was also produced by Rubin.

The song harkens back to the rapper's early tongue-in-cheek Slim Shady tunes, throwing in celebrity references along the way. Lyrical grenades are thrown at Khloe Kardashian and her husband, NBA star Lamar Odom ("ugly Kardashian/Lamar), and Britney Spears' ex with an increasingly large waistline, Kevin Federline ("So baby just make like K-Fed and let yourself go, let yourself go,"), whilst fellow rappers such as Kendrick Lamar, Birdman, MC Ren of N.W.A. and Public Enemy are all name-checked.
