Brazil just kicked off their annual Miss Bumbum competition

God we love Brazil.

The annual Miss Bumbum pageant started this week in Sao Paulo, and if the name doesn't give it away, it's a competition to find the best chick with the ass-ets. 

27 girls with cheeky outfits paraded down the streets of the city in the hopes that they'll make the top 15 in November.
