A word used to describe the weather. Presumably when it is could and chinchillas are falling from the sky. This, however is not the case, and it is just a gay way to say that it is slightly cold out.
Guy 1: "Man, it was so Chinchilly today."
Guy 2: "You mean it was cold, right?"
Guy 1: "Yeah."
Guy 2: "Fag."

Get the Chinchilly mug.
Chinchilli Day celebrates the victory of the tiny pueblo town of Topiticca over the uprising of their pet chinchillas. Although many attempts were made to negotiate a ceasefire, the fighting continued over three long days until the last of the chinchillas was gone. To this day the town’s victory is celebrated by the descendants of Topiticca and all chinchilla haters.

Note: Because little is known of the actual dates of the conflict, there are those who believe the town of Topiticca never existed and Chinchilli Day is actually an elaborate excuse to spend an extra day partying in Las Vegas.
I can't come to work Monday because I will be in Vegas celebrating Chinchilli Day
