Miley Cyrus and her booty are still twerking with the best of them. But don't get caught out by a twerk-talking teen, check out our beginners guide:

What is it?

Oxford Dictionaries announced that the booty-popping dance move would be in future publications as a verb, defined as "[dancing] to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance."

It's possible that the phrase is a combination of twist and jerk (kind of like how Brad and Angelina became Brangelina) or it could simply be a made up work.

When did this craze take off?

Don't let little Miss Disney, Miley Cyrus lure you into thinking this is her gig. Twerking has actually been around for 20 years.

Before Miley was but a twinkle in Billy Ray's eye DJ Jubilee released, "Do the Jubilee All," in 1993, which featured the lyrics, "Twerk baby, twerk baby, twerk twerk twerk."

Cut to present day and Miley Cyrus posts a video mimicking the moves, then twerks her thang on stage at the VMA's and BAM you have a 'craze'.

Why is it so popular?

Well for the more sensible of us, it’s a great workout for your bum and thighs, as well the deep muscles of the hips, lower back muscles and abs.

Twerking will shape and strengthen all those muscles as well as give them the stamina to do activities important to most people heavily involved in terming like say, picking up a screaming child off the floor.

How can I get my twerk on?

Watch this?

Failing that we're pretty sure you can can just shake your bum a lot in any which way and say you're twerking. It worked for Miley.
