Slug-rat

A slug-rat or slug rat, was a creature in the galaxy. It was also used as an insult. In 3 ABY, during a fight aboard the Crimson Dawn criminal syndicate's flagship the Vermillion, "Ren"—the leader of the group of dark-side practitioners known as the Knights of Ren—referred to the former pit fighter Tasu Leech as a slug rat when asking Leech how he had acquired a knife laced with beskar.
