Wizard Dinosaur 

A dinosaur who performs magical spells by rawring them at the person/thing they want to be affected. It's bones have not been found because scientists believe they put invisibility cloaks on them at their burials. Some say they have seen some.

The wizard dinosaur put in an imperious curse on me and I am now his minion. RAWR!

Un-dinosaur 

When a cat (often named Cat), who typically raises her back hair and bushes out her tail (causing her to resemble a dinosaur), begins to become comfortable around another animal (typically a canine christened after a type of dark alcohol), inducing her hair to return to normal. Usually a sign of affection or acceptance.

Hey Erin, look at how Cat calmed down around Scotch! She totally un-dinosaured!
