I don't know what it is about this song, but I love it. It's probably mostly to do with the video: a really innocent-looking smiley girl, with the pearliest of white teeth, in a Mickey Mouse top, singing/rapping obscenities and dancing like a cool, calm and collected crazy person. (You'll have to watch the video to understand what I mean.) And then there's Lazy Jay, living up to his name in the background.
Be warned, it's catchy!
