Speak for yourself. It simply means that we're the tenth generation born since the founding of the United States.
Oh, I thought it was simply that "X" is a "fill in the blank" connotation, and that since we just HAD to name the prior generation (the "Baby Boomers) - even tho no other had been named, w/o a clue to a good name, some1 somewhere just said "Gen X - fill in the blank!" Unfortunately the former stuck. And now we have Y, Z, AA, etc. Ridiculous.
I say, go back to naming the decades and forget names for generations.
