An adjective used to describe dogs named Rufus. Only dogs named Rufus can be shmoofy. A common nickname for Rufuses is “Shmoofy Roofy”. All Roofys are shmoofy, but they all have varying degrees of shmoofiness. It just so happens that my dog is the shmoofiest Roofy in all the land.
(Also yes, I’m aware that roofie is also a drug term, it’s just a cute nickname I have for my dog, ok?)
