Gilderoy Lockhart is the vain Defence Against the Dark Arts teacher from the Harry Potter stories, famous for boasting about his own achievements and posing for admirers. His drawn-out pronunciation of parfait fits that character perfectly, turning a French word for perfect into a self-congratulatory catchphrase. The short clip has since circulated on soundboards and in short-form edits, where creators use it as a quick reaction to flawless results, stylish moments and ironic self-praise. Its appeal endures because Lockhart's vanity remains instantly recognisable, even to viewers who only know him from memes.
