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!
