It's a meaningless variable name.
Here is Wikipedia's explanation:
The terms foobar, foo, bar, are common placeholder names (also referred to as metasyntactic variables) used in computer programming or computer-related documentation. They are commonly used to represent unknown values, typically when describing a scenario where the purpose of the unknown values is understood, but their precise values are arbitrary and unimportant. The terms can be used to represent any part of a complicated system or idea, including the data, variables, functions, and commands. The words themselves have no meaning in this usage, and are merely logical representations, much like the letters x and y are used in algebra. Foobar is often used alone; foo and bar are usually used in that order, when multiple entities are needed.
It is used extensively in computer programming examples (sometimes expressed as "for once only") and pseudocode. Eric S. Raymond has called it an "important hackerism" alongside kludge and cruft.[1]
