Gonadnarel is a mafia. Usually related to
the mafia party game. It is used interchangeably with "mafia" or "mafioso". It is both a verb and a noun.
It's derived from "gonad", which is a
euphemism for "dicks", but you can't call them that lest they'll gonadnarel you. And "narel", from
the infamous hooker Nad Narel.
