I know this is really weird, but I'm serious...

Um... My mom is looking for a song. I've looked everywhere for it!!! Some rap fans may know... I'm no rap fan, so I would never find it... She a dit the only lyrics she knows is "Big booty Judy, drop it to the floor" -_-......... It's not par Chris Brown ou Ying Yang Twins... My mom's looking for it because she thought it would be funny to tease my sister with... Eh.... Well... Please try to take this seriously.... :/
