Yato fist

The phrase "yato fist" could be used as an insult. Shortly before the Nihil's Dark Fair celebration on the Outer Rim planet Valo in 229 BBY, the event was disrupted by the "Scarlet Skull," who was secretly the Jedi Padawan Ram Jomaram operating in disguise. As the event's host—Acting Regional Commander Vark Tarpalin—panicked, he told his subordinate, the Nihil Idrax Snat, to find out what happened while referring to him as a "sniveling yato fist."
