Potato

A fruit.

Inside joke

And inside joke is something that Urban Dictionary doesn't allow in their definitions.

Urban dictionary: "Don't name your friends. We'll reject inside jokes and definitions naming non-celebrities."
Me: "Ok."

Goatly

Someone who is shaped like a goat or is incredibly awesome. Or both. Both is good.
