Quite. We can see SPQR on the manhole covers in Rome and know that the Senate and People of Rome own the place. That's a signature that is well over 2000 years old - it used to also appear on the "eagles" of the legions and in a fair few other places. That is a very well documented and understood message from the past. A few miles (mille passus) from me is Lendiniae - we call it Ilchester these days. The -chester name implies it was a Roman camp/town. What we are talking about here is context and history. Please share where you lot are from and some examples of how slang has changed for you. I might not understand it but I will appreciate it and it gets documented somewhere. There is a really good reason for the Internet Archive to exist. It remembers stuff. We've lost so much already but future generations will have rather a lot of data to pick over.
