I don't think the term is quite that bad, but the way we talk about it is. That said, my choice to use the term "puff" was specifically to avoid any pre-conceived notions about the duality.
The term "wave-particle duality" was coined because we can imagine waves, and we can imagine particles, and when we realised that we couldn't force light and electrons to be one or the other, that they must be, in some sense "both".
The term is not wave particle alternation, conversion, collapse, or any thing which implies that it is sometimes one and sometimes the other. However, the elementary examples we give people learning about QM might mislead people to believe that.
The "duality" is expressed specifically to indicate that it has both aspects at all times.
