First you called the guy a loon. Which means crazy. You offered the second definition of lunatic only after I pointed out that the primary meaning of lunatic means mentally ill. if you are not bright enough to know you are not fooling anyone by changing directions in midstream I don't really know what to tell you.
You continue to play with yourself. Perhaps you should find a suitable partner to help you with that.
Lunatic, like so many words which have multiple meanings, also means "wildly foolish" which, as has already been explained, is how I used it.
That you insist on applying YOUR meaning to my post isn't my prob, Princess, but rather yours and your continuing down that rabbit hole is a sure sign that you are a lunatic (and I'm now applying your definition).
