Even the dictionary is sick of his shit

Back in my day, it was used to describe massive monuments to the gods. I guess I'm just too old.

It is a very long list of words that have changed meaning or come into existence even in a short span.

Sub cultures like the vebetabke “surfer dude” and the “hippies” had been using words like these (including these) since at least the 1960’s, and such words were used in advertising under the more “modern” use since at least the 40’s and 50’s.
