Well, not just any old something -- Sir Mix-a-Lot got you "the ultimate 21st century booty-based app." And here it is.
While the actual release date isn't until May, you don't have to wait to get it, as the "fully-packed with a buttload of hands-on features including the Mix Makeover photo lab, the Ba Dunka Dunk club game, Sir Mix-a-Lot's Booty Calls, a social media Text Mix and more" is available now.
App users who don't necessarily got back will be happy to know that one of the features will allow them to manipulate photographs of themselves or their friends and stretch any of the visual assets to their liking. Shake that nasty butt!
