foo

A (presence/force/being/no one really knows) that is the biggest threat to our civilisation and could collapse all economies around the world in an instant. Luckily the Foo fighters have been fighting the foo and protecting our delicate social constructs from this almighty enemy.

foo

foo A sample name for absolutely anything,
especially programs and files (especially scratch files).
First on the standard list of metasyntactic variables used
in syntax examples.

The terms foobar, foo, bar, and baz are sometimes used as placeholder names (also referred to as metasyntactic variables) in computer programming or computer-related documentation. They have been used to name entities such as variables, functions, and commands whose purpose is unimportant and serve only to demonstrate a concept. The words themselves have no meaning in this usage. Foobar is sometimes used alone; foo, bar, and baz are sometimes used in that order, when multiple entities are needed.
