Homework Help?

I'm going to do something I've never done before....I'm going to use my blog to get what I need. Or want. Or...need. Heh.
So anyways. I'm doing a research project on the influence that post modernism (modernistic?) views have had on the English language. (i.e, the word "gay" used to mean happy, but now there are some people in this generation that don't even know that, etc)

So I would be forever grateful if you could:
A) Comment with some words that you can think of that have undergone severe (or not so severe) meaning changes in the last 50-60 (or longer) years.
B) Ask your parents, friends, grandparents, aunts, uncles, cousins, siblings, etc, if they can think of any.
C) Uh...I don't think there is a "C"...but if you can think of another way to help, more power to ya :)

So yeah. If you could help out, that would be awesome! And in like two weeks or so, I'm going to come back and be begging for help again. So if I see my number of followers dramatically drop, I'll totally understand ;)

P.S...It wouldn't hurt to point more people in the direction of this blog either. More followers is always a plus :D
Please & Thank You!
