Britney's kinkiest and trippiest single since "Toxic," if not ever, becomes a trash-disco Yalta. Co-writer Ke$ha drawls over the slowed-down sleaze-bot groove. But Minaj makes it a keeper; she sneers, "I ain't talking poultry when I say this chicken's friiiiied," as synthesized fowl cluck along, summing up this remix's wild humor.
