Beer which one "discovers" having not known that it was there. Typically this occurs after a party or family gathering/event and may often involve a secondary fridge or forgotten cooler. Discovery of said beer is usually followed by feelings of joy and well being, similar to finding unexpected money in a jacket one has not worn in some time.
I'll just clean out the fridge, haven't done that in a while... wait a sec what's this? BONUS BEER! Righteous!
