I can think of ten words that people will say the same of in 200 years. Some in just 50.

Yeah, I think the meaning of the word "decimate" has expanded over time, as definitions tend to do. freedictionary.com:

dec·i·mate
1. To destroy or kill a large part of (a group).
2. Usage Problem
a. To inflict great destruction or damage on: The fawns decimated my rose bushes.
b. To reduce markedly in amount: a profligate heir who decimated his trust fund.
3. To select by lot and kill one in every ten of.

fuckin trust funders

Actually the "usage note" following that definition is kinda fascinating:

Usage Note: Decimate originally referred to the killing of every tenth person, a punishment used in the Roman army for mutinous legions. Today this meaning is commonly extended to include the killing of any large proportion of a group. Sixty-six percent of the Usage Panel accepts this extension in the sentence The Jewish population of Germany was decimated by the war, even though it is common knowledge that the number of Jews killed was much greater than a tenth of the original population. However, when the meaning is further extended to include large-scale destruction other than killing, as in The supply of fresh produce was decimated by the nuclear accident at Chernobyl, only 26 percent of the Panel accepts the usage.

How do I get to be on the "usage panel"????

You have to be a combination of jaymc, la lechera, and Superman.

that would do it, surely

I am neither Jewish nor fresh produce, so I doubt I would have a place on the panel.

Inside information: the anti-fresh-produce lobby totally rigged that election.

See these 'usage panels' are exactly the kind of thing Sarah Palin was trying to warn us about!
