Top definition
foo bar is very often used in computer programming, used to declare a (temporary) variable.
Most probably, "foo" and "bar" came from "foobar," which in turn had its origins in the military slang acronym FUBAR. The most common rendition is "Fucked Up Beyond All Recognition"
Suppose we have a function named bar and a variable foo. To call the function we use foo bar.

A slang term meaning "fucked up beyond all recognition." The saying was used primarilly in programing and originated as fubar, but for political correctness it was changed to foo bar.

Foo and bar also often represent variables.
Dude that thing is foo bar!

1) What basement dwellers say when they can't come up with anything. The writer prefers meow. (see also: swedish chef)

2) A very configurable media player. There is that form vs function prob though, so it takes a month to figure out the volume control, and you'll still bitch it out all the time. Can play and rip at the same time, which is nice. (aka foobar2000 foobar2k fb2k fb)
