In 2015, it seemed like every celeb-from Rita Ora and J.Lo to Kim K and Beyoncé (you get the idea)-was flaunting their nearly-nude derrieres on the red carpet, motivating the rest of the world to start working on their squats, stat. But those booties inspired others to take more extreme measures, even so far as going under the knife to achieve a perky backside.

According to the 2015 report from the American Society of Plastic Surgeons (ASPS), butt implants and lifts are the fastest-growing types of plastic surgery in the United States. The trend started in 2014 (AKA 'the year of the booty'), and is clearly here to stay: On average, there was some sort of butt procedure every 30 minutes of every day in 2015. Say what?!

The stats show that there were over 22,000 derriere-focused procedures last year-including butt augmentations with fat grafting, which were up 28 percent from 2014; butt lifts, up 36 percent; and butt implants, up 36 percent since just last year. And new tush-friendly technology has allowed surgeons to remove fat from one area of the body, inject it into the butt, and have it stay in the perfect mold they create.

Boob jobs, nose jobs, liposuction, eyelid surgery, and facelifts still beat out butt boosts in terms of sheer numbers, according to the report. (Before you go under the knife, see the 12 Things Plastic Surgeons Wish They Could Tell You.)
