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.

Like Pig-Latin:
A language from who-knows-where that is actually a variation on English.
Also known as "Gibberish" and "Double Dutch".

It is spoken by putting the sound 'inag' between each syllable. If the word starts with a vowel, put 'inag' first, if starting with a consonant, after the first syllable.

After much practicing, it can be spoken VERY fast, sounding VERY cool. And other people can't understand you.

I know people from across the province who can speak it.
