I thought you were just mistaken about something, but no, instead you've redefined a well understood term without telling anyone, then aggressively refused to clarify what you meant by it and argued for hours with people, while saying they were all wrong when they used the well established term to mean its well established meaning.
The thing you're talking about is an interesting concept, but it's not called dynamic dispatch, and you will confuse everyone you talk to if you call it that. I don't know if there's a term for it.
