Randy Savage became one of professional wrestling's most recognisable stars as Macho Man, famous for his colourful outfits, intense interviews and quotable promo delivery during his WWE run. Lines like this one lived on long after his wrestling peak because fans clipped his promos for highlight reels, reaction videos and soundboards. The phrase works as internet shorthand for total confidence, so creators keep reusing it whenever someone is completely, almost absurdly sure of themselves, keeping Savage's larger-than-life persona alive for audiences who never watched him wrestle live.
