In March 2013 Miley Cyrus posted a video of herself wearing a unicorn onesie (and her engagement ring) doing a dance known as "twerking".

UrbanDictionary describes "twerking" as "The act of moving/ shaking ones ass/ buns/bottom/buttocks/bum-bum in a circular, up-and-down, and side-to-side motion."

Whatever the dance technically is, Miley Cyrus got everyone is talking about her moves:

Aly Weisman explains Jay-Z mocking Miley:

In Jay-Z's single "Somewhereinamerica" off his new album "Magna Carta Holy Grail," the rapper seemingly mocks Miley for her skills.

Here's the lyrics:

When I was talking Instagram/ Last thing you wanted was your picture snapped/ Feds still lurking/ They see I'm still putting work in/ Cause somewhereinamerica/ Miley Cyrus is still twerkin', ha!

Twerk, twerk, twerk, twerk/ Twerk, Miley, Miley, twerk/ Twerk, Twerk, Miley, Miley, Miley, twerk/ Twerk, yeah, ugh-huh/ Twerk, Miley, Miley, Miley/ Only in America.

But whether Jay-Z is mocking or praising Cyrus, the singer has one definite fan in Nicki Minaj.

"I love her Twerking moments. That's what is is all about being an artist," said Minaj. "She is so damn cute and down to earth. I really love her."

As for Cyrus, she says she's been working on her twerking for quite some time now.

"You can't really explain [twerking]," she told Ryan Seacrest on his radio show. "It's something that comes naturally … It's a lot of booty action. I've been practicing probably for the past two years, in my own time in my living room."

"I can't believe how many people think I'm good at twerking — which is dope, " Cyrus added. "Like my life goal has been accomplished."

I thinkn Miley Cyrus needs more important life goals.

Any questions?

Miley Cyrus is very comfortable being herself.

For that, I commend her.

Btw, Jay-Z's deal with Samsung buying 1 million copies of his album for $5 million is historic:

Jay-Z is not a businessman. He's a business, man! And he's really into big data...
