What does 'foo' really mean?

It is a very common thing to encounter in php.net statements like $foo="bar" or other such statements. Is there any significance of foo and bar or are they just conventions evolved as a matter of time?

One quick wikipedia lookup away: http://en.wikipedia.org/wiki/Foobar — ChristopheD, Jun 03 '12 at 19:14
Being at a bar, he was drunk... missed the 'd' when typing up his report, hence we know it as "foo" — jdl, Jun 03 '12 at 19:25
the only convention i know of is that bar is generally used after foo in examples. — goat, Jun 03 '12 at 20:28

Nobody's entirely certain of the origination of the two terms, but there are theories.

It's a lot like Hello, world!. It simply caught on.

No, we are actually "entirely certain". – DOK Jun 03 '12 at 19:15
Where did they originate, then? – Litty Jun 03 '12 at 19:16
