Absolutely. You have absolutely misused words to mean something quite opposed to their actual meaning, and when called out on it, you have used the 'words mean exactly what I want them to mean whenever I want them to mean that' defense.

Although, truth be told, it was not "to your advantage", as it was an egregious transparent act of disingenuosity ( <- alas - probably not available in the dictionary) fooling nobody, and therefore gaining you no advantage whatsoever.

Nothing egregious of late, this is true. But Pepperidge Farm remembers. As, no doubt, do you. Dissemble no further!
