I just looked it up and that is not to be found. Oh, I see what you did there. Coined a new definition for "definition". You're nothing if not thorough .. thorough obfuscator, thoroughly mistaken.
Ahahaha that's very smart!

I'm purely reasoning using logic and i suspect you're not - though you're welcome to prove me wrong.
