ITAW for when a phrase describes something factually wrong, but we go along with it anyway?

For example, The "low man on the totem pole" is actually the more important one because you see it with the most detail. Or drinking the Kool-Aid was not, in fact, Kool-Aid. A "Quantum leap" would actually be the smallest leap possible.

Edit: Haven't found one. But I'm gonna make one up: Twisted Idiom
