With the weather being a bit whacky at the moment it’s time for a whacky MMM. Major Lazer have released the video for 'Bubble Butt'.  SPIN’S 40th best song of the year comes from the Diplo-led project's second album 'Free The Universe', and features Bruno Mars, 2 Chainz, Tyga and Mystic. As it's a Major Lazer production, it's a given that the Eric Wareheim (of Tim And… fame) directed video is whacky, and that it's concerned with a certain area of the female anatomy.  This time, the bubble butt. The best part?  A blatantly fun and ridiculous track.  The problem?  The year's catchiest chorus you don't want to be caught singing in public.
