Steve Austin popularised the 'What?' chant during his WWE run in the late 1990s and early 2000s, using it to heckle opponents and stall promos while crowds joined in. The routine became one of wrestling's most recognisable audience participation moments, and clips of it spread through wrestling compilations, reaction videos and soundboards. It endures because the format is instantly understood: one word can turn any boast, excuse or argument into a running gag.
