I first started reading about the concept of being a locavore this year, and love it. It's one of the most effective ways to really live "green." Huge amounts of energy are wasted on transporting foods.
I guess this issue itself has now become somewhat disputed and controversial. Sometimes, apparently, it's more "green" to eat things that are grown, manufactured, processed, packed and/or shipped more efficiently, even if farther away.

Anyway, back to the buzzwords, I find it easier to pick the ones I've heard of than the ones I like. They are:
cougar (on "30 Rock")
surge (from Bush himself, I think)
Colbert bump (from Colbert himself, for sure)
vajayjay (all over the place)
My most fun way of acquiring a buzzword -- well, a slang word -- was "ballin," which has to do with affluence/status/the good life. One day my 13-year-old son said something or other was ballin and I disagreed and said it wasn't and he said "You don't even know what that word means." But I did! I had heard of it from 75-year-old TheFullMontyClift! Who'd heard it from 50-year-old littlewing! So ha ha ha.
