I'm not even sure how to spell this, but when my brother and I were too wiggly as children, our parents told us not to be so "rootchy" (rutchy? Same "oo" sound as "book"). When we were stubborn, they borrowed from Richard Scarry and told us not to be "pig-won'ts".

My 1986 Nissan station wagon was the "gerbil", presumably because it was tan and had white license-plate "buck teeth".

Bill D--we once had a dog named Ootek, who had many nicknames, one of which was "Ooblek". What an awful thought! (On the other hand, he was also called Oozie).
