"Bubble Butt" (SPIN's 40th Best Song of the Year so far) is the secret gem of Major Lazer's Free the Universe — a flagrantly fun and ridiculous track with the year's catchiest chorus you don't want to be caught singing in public. It won't be a secret much longer: Diplo commissioned frequent collaborator Eric Wareheim, of cult comedy duo Tim & Eric, to direct the song's video, and it's the type of absurdist and self-consciously provocative video that helped create Major Lazer's mythology. None of the song's stars — Diplo, Bruno Mars, Tyga — appear in the video, but considering it depicts women getting their butts literally inflated, that probably makes sense.
More importantly, the video features a short eight-bar verse from 2 Chainz, who was all but born to rap over a beat this springy with a conceit this specific. Sometimes, the planets align.
