lol, it's not a "you do you" thing, that's what they're actually named, "parameters" and "arguments" have distinct objective definitions in this context and those are it. In this specific case it's you who's using made up words for concepts that others already have a specific name for.
> that's what they're actually named
...by what authority? c'mon, communication is important, and insisting on the correctness of definitions tanks that.
EDIT: however, I will concede there's good evidence for widespread usage of this, and I'll adjust my usage accordingly. Insisting on "correctness" is just asinine, though.
