What the hell is a “koozie”?

My Autocorrect even changed it to “kookier”.

It's the foam rubber thing you put around your beer to keep it cold. Also it may act as a coaster and stop the can from leaving a stain (maybe).

It was a "cozy." Now it's a "koozie." "Koozie" is trademarked, so if people keep calling it that they may lose the trademark protection.
