Low-rise pants and big-butt beauties like J. Lo and Beyonc‚ have put the “ass” back in asset for the large, round rear end in mainstream America. But will New York’s newest seam-busting-at-the-butt mannequins have customers asking, is that mannequin too bootylicious for you, babe?

Established companies like Macy’s and Saks are picking up on a trend that started on plastic figures on the streets of New York City and Los Angeles. Brands like Guess and EckoRed have created a new mannequin to display their jeans that have a large, more full-bottomed backside — a superior posterior, if you will.

According to mannequin firm officials, consumers are hooked and they can’t stop starin’. Dwight Critchfield, creative director for the mannequin firm Goldsmith, told Reuters the mannequins with engorged hindquarters have “a real sex appeal about them.” Since EckoRed first started using the larger-butt mannequins — aptly called the J. Lo butt — nearly two years ago, its sales have tripled.

Women like it because the mannequins more accurately portray their body shapes. Men like it too — so much so that guys are going into stores just to buy the mannequin, The New York Times reported.

Back that thang up because this is a rump revolution. We’re tired of magazines saying flat butts are the thing. Since stars like J. Lo and Beyonc‚ bum-rushed the scene, women with junk in the trunk have had role models. Mannequins with fabulous fannies solidify that the butt is back, meaning no more starving actresses who look like 10-year-old boys will serve as the ideal sex symbol.

Fashion in: Bountiful butt. Fashion out: Female “Friends” stars who developed a skeleton complex during their 10 seasons on NBC.

The trend’s move to department stores couldn’t have happened too soon. Mannequins modeled after size 2, 6-foot runway models like Twiggy alter the perception of what a real woman ought to look like, even if the form is unrealistic. The result: Young girls starving themselves to fit into this unhealthy prescribed beauty mold, depriving themselves of essential nutrients and dwindling into anorexic oblivion.

The Iowa State Daily editorial board, as the campus connoisseur of a derriere extraordinaire, endorses large-butt mannequins as a progression toward a healthy, more voluptuous society. Put your gluteus to the maximus and shake it like a Polaroid picture. Women’s bodies are inherently beautiful and have been idolized since the days of the Mother Goddess. Take pride in what your momma (and papa) gave you.

Sir Mix-A-Lot provides the best advice: You can do side bends or sit ups, but please don’t lose that butt.
