Needs Help: Greeting Gesture Confusion

I recently launched this trope, and it occurred to me only after I launched it that "Greeting Gesture Gaffe" would be a much better name, both for getting across the sense of the trope better and for the Added Alliterative Appeal.

The current name is absolutely fine, I'd just prefer to rename it if that's alright with everyone.

Under discussion here, so I'll relay.
