If Twerking is Egwu-Ukwu Reloaded, What Do You Think of the Oxford Dictionary Definition?

I got introduced to the word twerking just a few days before Miley Cyrus blew up the internet with her version of the dance at the MTV video music awards [see here]. Someone send me a video of a compilation of various people twerking and said, is that not Egwu-Ukwu (translate - Dance of the hips)?

I don't know what it is called in other Nigerian languages, but there's this dance movement in most Igbo free-style dances where the lady kinda rolls her hips. Owerri women, I think, have a special variation on this dance move, as well as Yoruba women.

In fact, I watched a dance troupe from Ogwasi in Delta performing this dance three years ago without knowing it had an American name already. They even did the style where you spread your legs, put your hands on the ground, and shake what your mama gave ya. As you can imagine everyone, especially the men went wild. What I have not seen traditional Nigerian women dancers don't do sha is stand on their hands with legs in the air and do the dance.

Now, twerk is an official word in the Oxford online dictionary as seen above. What do you think of the definition? Can we call the Nigerian Egwu-Ukwu Twerking?
