For some reason, MSN decided to do an annoying slideshow of slang terms and where they came from.  But the best part is looking at the evolution of slang terms for the word "cool" over the past 100 years.

It's amazing how we still use a lot of these today . . . not.  (--See what I did there?) Here are 29 ways to say something's "cool" over the past 100 years.  And if some of them sound stupid, just think how lame WE'LL sound in a hundred years.
