Stone Cold Steve Austin, one of WWE's most popular stars, turned 'What?' into a signature crowd interaction during his in-ring promos, with audiences shouting it back after almost every line. The chant became a defining part of his rebellious, anti-authority persona and was heard throughout WWE broadcasts in the Attitude Era and beyond. As clips circulated on soundboards, video edits and social media, the single word became shorthand for disbelief and defiance, which is why creators still reach for it when they want an instant wrestling-flavoured reaction.
