look up any word, like donkey punch:
A "Baumer day" includes staying home instead of going to school for a list of various reasons. Including but not limited to: Late hockey game, lost a hockey game, too much work to do, had to work the night before, or even just wanted to take a day off.
Griffen: hey guys have you seen Chris?
