Why this word is great
WHIPPERSNAPPER — [Noun] A presumptuously impertinent young person, whose cheeky overconfidence is underwritten by pure inexperience. The term is an extension of *whip-snapper*, meaning "a cracker of whips," likely referring to a young person idly snapping a whip; possibly influenced by similar reduplicative forms like *snipper-snapper*. Unlike an "upstart," whose arrogance springs from a grating ascent in status, or a "neophyte," a neutral term for a beginner, a whippersnapper is defined by the galling friction of raw youth against settled decorum. He is the know-it-all interjection that halts a grandfather’s story, the apprentice correcting the master craftsman, the unsolicited advice delivered in a cracking voice—the fleeting, infuriating noise that every generation must eventually learn to ignore.
