A word for the unwise.

What is this sudden urge to name actions that we have all been doing for years? Since the invention of the camera people have taken photos of themselves. Now we call them "selfies" as if it had never happened before and it is somehow worth commenting on. It isn't. Also from the earliest days of cameras, some idiot has leapt into the picture or appeared accidentally or done that dumbest of all dumb moves: put two fingers over someone's head. Now it is called "photobombing" for no good reason. What's next? Will there be a new name for interrupting a conversation, for asking a dumb question, for using the wrong word? I have a new word, based on the word lexicon, it means a newly created word for no apparent reason: lexy.
