My mate summed up Booty really well - he said that it gets girls dancing like nothing else and is really brilliant for about 45 minutes and if you hear it for any longer it makes you want to kill people.
On a sorta related topic, has anybody checked out Funky Do Morro / Favela Funk? From the ghettos of Rio, it's music made on simple rigs by kids who grew up listening to too much Miami Bass. http://evil-wire.org/~ampere/mp3/funky/ is the motherlode - a big old pile of Brazilian Booty to help yourselves to. Diplo is heavily influenced by this style.
