But you probably have seen the standard example variable names "foo" and "bar" which (together at least) come from `fubar`

[sunnybeetroot]

Which are in fact unrelated.

Unclear. ‘Foo’ has a life and origin of its own and is well attested in MIT culture going back to the 1930s for sure, but it seems pretty likely that it’s counterpart ‘bar’ appears in connection with it as a comical allusion to FUBAR.

Foobar == "Fucked up beyond all recognition "

Even the acronym is fucked.

My favorite by a large margin...
