I would LOVE to hear the logic behind this bit of sophistry!
The meaning of a word is the common usage of that word. It really isn't that difficult to figure out.
Language is a *convention*. Words do not have meanings other than how they are used.
So, if everyone except you is using a word in a certain way, *that* is the definition of that word. if you are using it in a different way, then you are using it incorrectly.
The meanings of words also change over time and from location to location. But, if you are the only one using a word in a particular way, then you are the one abusing the language, not everyone else.
