A decade ago, women were augmenting their backside shape by silicone implants. On the other, there is an increasing number of women enhancing the size and modifying their butts shape by fat infections, a better process called Brazilian Butt Lift. This procedure could increase one to two size of the butt size, costs around $10,000. Cultural obsessions with butts, who started it?

At this year's MTV Video Music Awards, Nicki Minaj, thrust her backside on air and gyrated her hops on stage, dressed in a green sequined two-piece, as she performed her latest hit, Anaconda. She sang, "Oh, my gosh, look at her butt/Look at her butt/Look at her butt."

The singer was joined by Ariana Grande and Jessie J, and went onstage to sing Bang Bang. The first few lines of the song, "She got a body like an hourglass/But I can give it to you all the time/She got a booty like a Cadillac/But I can send you into overdrive."

The same night, Rita Ora and Iggy Azalea, performed, Black Widow, Jennifer Lopez shakes her booty with Azalea Booty, which previously fell. The track's original version was launched on JLo's A.K.A album. The chorus goes, "Big, big booty/what you got a big booty." In the remix, Azalea's lines, "The last time the world seen a booty this good it was on Jenny from the block," It was true, after all.

In 2000, JLo showed her butt and started the butt fad, with her derriere-hugging, plunging, Versace dress during the Grammys, when she attended the program with see-through green dress. According to an interview with a Miami-based plastic surgeon, who wrote The Art of Gluteal Sculpting and an internationally famous expert on the issue of butt enhancement, he said to Style, "After they saw her, people started asking us, 'Hey, how can I get a backside like that?'" That started women and men, obsession with big and nice butts
