virginilante
Da non-existent "portmanteau" word dat Mork From Ork was actually thinking of when Mindy --- alarmed at Mork's naively "taking the law into his own hands" by shooting out streetlights in an effort to save electricity --- asked him if he knew what a certain term meant; he told her that it refers to a guy who's looking for a "vigilin" --- i.e., girl who hasn't yet been "deflowered". "Vigilins are an endangered species nowadays".
Perhaps a "virginilante" could also refer to someone who tries to maintain the "unbroken" integrity of young ladies' maidenheads until they get married.
