The rhyme comes from the traditional children's playground taunt commonly rendered as liar, liar, pants on fire, passed around schoolyards for generations as a sing-song way to accuse someone of fibbing. This soundboard version twists the wording to panties, a silly variation that makes the chant feel even more like an internet meme remixed for shares. Its spread follows that wider pattern of playground rhymes being clipped, reposted and dropped into reaction edits, where instant recognition matters more than any single original recording or performer.
