$foo $bar is BAD

*Although people commonly use $foo $bar in examples, it is actually a
misuse of a VERY rude acronym.Anyone that has done time in the military,
and other goverment agencies, has been introduced to the term fubar, which
stands for "fouled up beyond all repair". Although fouled was replaced by
another similar word where the 2nd, 3rd and 4th letters were substituted
with other letters that gave more significance to it. Over time, fu was
somehow misheard as foo, and coders commonly started using it in examples.
Not Cool!*

*The next time you need to make an example, please try being a little more
original (or meaningful) with your variable names.*
