Nas responded with the scathing "Ether" later that year. The song so effectively tore into a seemingly unflappable Jay Zthat "ether" has become a slang verb of its own. The song—and the battle—reenergized Nas on his acclaimed, double-platinum fifth album, Stillmatic, which, as the title suggests, found Esco returning to his street aesthetic of his classic debut. Jay replied with the ultra-personal "Supa Ugly," which revealed that he'd had a relationship with Nas' baby's mother, but it fell flat, and Hov quickly apologized. Nas was widely declared the unlikely victor in this clash of the titans.
