Google is your best friend.

The origins of the terms are not known with certainty, and several anecdotal theories have been developed to identify them. Foobar may have received the abbreviation FUBAR from the military and gained popularity because it is pronounced the same. In this sense, it can also come from the German word furchtbar, which means terrible and terrible.
