Eminem's freestyle rap slurs Caitlyn Jenner

Kelly Lawler | USA TODAY

Rapper Eminem, whose lyrics have tended to court controversy over the course of his career, performed a freestyle rap on Thursday's Sway in the Morning show that contained a transphobic slur against Caitlyn Jenner.

“I invented prick, and that’s a true statement, I see the (expletive) in you, Caitlyn / Keep the pistol tucked like Bruce Jenner’s (expletive),” he rapped. After pausing he also added: “No disrespect though, not at all, no pun intended, that took a lot of balls.”

The rap also contained shots at Donald Trump and Bill Cosby, as well as references to violence against Miley Cyrus. “I’m (expletive) worse than Donald Trump / On Lexapro in Mexico across from a Texaco in a McDonald’s drunk."

"I made monopoly off misogyny,” he rapped at the end of the freestyle, and then referenced the sexual assault allegations against Cosby. “No wonder you scoff at me, it’s obvious I’m as off-putting as Bill Cosby is / Treat women like property, possessive like a noun with an apostrophe.”

Of Cyrus he rapped, “I’m coming through like a wrecking ball / You would swear I think highly of Miley / And I respect her the way I backhand her,” he rapped (with “backhand” sounding much like “back Hannah,” potentially a reference to Cyrus' old Hannah Montana character).

After finishing his freestyle, Eminem said it was all spontaneous and not intended to be a personal insult against any of the figures he mentioned. “I just say (expletive) to say it. It’s very rarely personal,” he said. “If it was personal, somebody would know. It’s all in fun.” You can listen to the freestyle here, although it contains the very strong and NSFW language described above.

This is only the latest instance of the rapper causing a stir. Eminem's lyrics have been a point of contention his whole career -- a 2000 profile of the rapper by the Guardian labeled him a "misogynist, homophobe, (and) hero." In the fall of 2014, he freestyled about punching Lana Del Ray before threatening to rape Iggy Azalea.

The rapper recently released a new single, Kings, featuring Gwen Stefani, part of the Shady Records-produced soundtrack for boxing movie Southpaw, which opens in theaters this weekend.
