Well, it all began when I was trying to hunt for a domain name for my blog. I had NO IDEA how saturated my name was on the web at the time - every single possible combination I could think of was taken or parked by someone!
foology, foolosophy, foozilla, fooking, foontastic, powerfoo, wonderfoo, footopia, fooie, fooster, foofamily, thefoo, tcfoo, imfoo.. they were ALL taken (.coms).
And the reason is because Foo does have a pretty rich history AND meaning (and I’m not talking about a Chinese heritage).
Foo is a GEEK. Term.
Foo is used all over the world in programming code, as a ‘metasyntactic variable‘. In programming terms, Foo means… nothing. Literally. It’s the name you give something to mean “this thing has no name.” It means “fill in your own variable name here.”
So programmers who know me, end up thinking of me all the time huh? I am whoever you want me to be.
According to the New Hacker’s Dictionary, it also has this meaning
foo: /foo/
1. interj. Term of disgust.
Amused yet? Anyway I dug deeper to try and find out why Foo was so commonly used in programming languages next to other variables like “Bar”, “Baz“, “Waldo“, “Fred“, “Thud“, “Quuz” and “Plugh“.
Apparently during WW2, soldiers used the term Fubar to basically describe something as being “Fucked Up Beyond All Repair“. Maybe I really am fubard.
There are people that believe this popularized the usage of Foobar and Foo and Bar separately in the programming circles. Then again, there are researchers who feel that the usage of Foo predates WW2.
Okay, so where does Foo really come from then? Apparently from THIS.
See my name on the vehicle?
Thats a very popular newspaper comic strip called Smokey Stover that first appeared in 1935 and was distributed by the Chicago Tribune Syndicate.
It also apparently influenced the term “Foo Fighters” which was used to describe small globes of unidentified light that were spotted both by pilots and radar and chased British and German fighter planes during WW2. In the comic, Smokey Stover often called himself a FooFighter when he’s actually a firefighter.
By the way, Yes - that’s where Dave Grohl’s band name came from.. (the UFOs not the fireman) 
Now that we are here, say hello also to Foo Foo!
The first ever British animation to be broadcast in the US (1965).
“… titled after its innocent clown-like star. Foo Foo’s heart was stolen by the attentions of young Mimi, but his rival in love, Gogo, was always coming between them. Optimistic Foo Foo was never beaten easily, though, and he would work around the problem somehow, defeat the bullying Gogo, and win his way back in to young Mimi’s affections…”
How sweet
And something not so sweet..

Ok, ok, I admit that was a bunch of pointless information you guys didn’t need to know 
I am simply.. Foo
