My Queen Anne pistol is yclept "Whangdepootenawa", a truly descriptive term first defined by my spiritual mentor Ambrose Bierce in his "Devil's Dictionary". Haven't come up with a polite name for my old CVA Kentucky rifle yet, though I'm leaning toward "Infernal Machine".
While on the subject, I've named all of my automobiles over the years: '63 Beetle ":Triumphal Juggernaut of Cthulhu"; early 70's Vega "Yellow Coprolite"; '72 Cadillac Sedan de Ville "Enterprise"; '92 Miata "Rosebud".
Named my two kids, too.
