This guy won the Internet for a while.
“I love learning the words that their generation comes up with â€” both the unique ones as well as the ones where they take an existing word and give it a completely different meaning.”
One of my favorite web sites is Urban Dictionary because people apply new meanings to words and phrases faster than official dictionaries track.
I first became cognizant of this in my teens. My mother had acquired a document from her school principal describing the symbols and words used by children indoctrinated into Satanic cults. To me, they mostly seemed benign things I associated with my friends into heavy metal music. And, of course, Dungeons & Dragons which I played at the time. Teenagers seek ways of communicating where parents are clueless.
Later, my second employer subscribed to various IT industry magazines. As I often stayed after close on Friday afternoon, he would engage me about things he read. I ended up getting free subscriptions to be able to better converse. The more I read, the more I understood jargon in IT mainly coopted existing terms for new things.
I also learned about how these new terms were poorly defined and understood at first. Only as they became super popular and everyone talked about them did their meaning get solidified into something real.
Finally, there is something unsettling at how African Americans continually are the bleeding edge of culture in the US. The music, clothing, and even terminology is sometimes adopted up by the overall culture. At the same time it is reviled as dangerous and feared for how those expressing it are doomed to go to Hell.
