Girls (mostly hipsters) who take up hoola-hooping or "hooping" as a serious form of exercise, socialization, and popularity. They will follow hooping as a fad and "hoop" whenever there is a camera present, or when other "hoopsters" are hooping in public to show other people that they hoop. Overly sensitive and defensive when anyone other than them mentions the subject in a non-glamorous light.
"OMG that kid is SO amazing! SHE'S A MINI HOOPER!"
