You are clearly out of your mind at this point. That's not how "real world definitions" work. Definitions aren't made out of a list of things a word isn't.

Besides, both sides of the equation are not equal claims. You took money from this person. You said you would refund it -- you lied. Instead of repaying them, you made up an arbitrary figure that you said was owed to you as an excuse to not have to follow through with your word. You are a thief and a scammer.
