USA East Coast = U 2b
Hey, I actually have an answer now that I think about it. Boob Tube was a term for the television about t5 years ago. Boob is not a breast all the time. Sometimes boob is used for a person that does nothing and has no thoughts. Tube is a name for the old style TV that was a huge glass bulb. So Boob tube is a pretty good term for that.
You tube, replaces boob with you, because it is not "for boobs" - Rather it is authored by You. So You tube replaces Boob tube. If you know how to say "boob" 'tube', you shall now know how to say You Tube.
