Foo, bar and baz are to generalized identifiers what i, j and k are to loop counters. They're not ideal, but they get the point across without taking the emphasis away from the underlying constructs. Are foo, bar and baz understandable terminology people can relate to like dog and bark? Not always. But if you don't speak English, dog and bark may make the same amount of sense as foo and bar.
