What is the origin of the word "Boob"?  
The "B" is the aerial view, the "oo" is the front view, the "b" is the side view.

...you can find ONE euphemism you like from this list....

I have NEVER liked that word.  Nor most of the synonyms.   Whatever happened to "breast and bosom" ???
Just a rant of sorts

They went out of fashion in the Mauve Decade.
