They are copying the Brazilian contest which is based on how big and shapely the contestants booty is and according to the article "A seven-member jury judged the contestants by the 'roundness, curviness and firmness' of their bums." Personally I do not see any curvy or round asses, just mostly firm.
I feel what you saying but being asian I judge them as such.
And even in your quote you say it's being judged differently.
And I didn't know Brazil had a monopoly on butt contests.They just popular for having big asses.
Im sure in Brazil a big raggedy ass would lose to a slightly smaller more toned ass.
You honestly expected them to walk out there with huge cement asses?
