The Rock's popularity continued to grow and audiences still cheered for him even though he was a heel. He then lost the title rematch against Stone Cold Steve Austin at . The next night on "Raw is War" he was fired from the Corporation after he was betrayed by Shane McMahon, turning him face again and starting a feud with Triple H, The Undertaker and The Corporate Ministry. On April 29, 1999, WWF aired the pilot episode of "SmackDown!", a term derived from one of the Rock's catchphrases. In the episode, the Rock continued his feud with The Corporate Ministry. This led to a match with Triple H, at Over the Edge, which the Rock won, and a match for the WWF Championship against The Undertaker, at King of the Ring, which the Rock lost. The Rock then lost a number one contender's match to Triple H, at Fully Loaded, after interference from "Mr. Ass" Billy Gunn. The Rock then defeated Gunn in a Kiss My Ass match at SummerSlam. The Rock was also given the privilege of having his own signature match, like The Undertaker with the Buried Alive match, Kane with the Inferno Match and Mankind with the Boiler Room Brawl: the Brahma Bullrope match, a variant of a strap match was a normal singles match where the components are tied together with a rope used for cattle farming, and the rope and its attached cowbell could both be used as weapons. The Rock contested this match twice, both times in Texas (vs Triple H in Dallas, and vs Al Snow in Houston).
