What's your point? It's 60 years old therefore can't possibly be stupid?

Or perhaps you have no point and are just nitpicking that I called it new? Compared to the word "to understand" it's new, it's pretty obvious that my use of the word new had a context attached.

You just asked us if we need new slang words. The answer is so self-evidently obviously yes that no one can actually understand why you bothered.
