Miley Cyrus -- You're Screwing Up Our Dance ... Nae Nae Creators Say

Miley Cyrus' version of the "Nae Nae" is total crap ... so say the guys who created the dance -- and based on the video they sent us, it looks like the Toonz wanna teach her a lesson.

Miley appeared on an Australian morning show this week and taught the hosts how to "Nae Nae" -- or so she claimed ... because the Toonz weren't impressed.

Watch the fellas call her out in this video -- they even included a how-to on the RIGHT way to do it, but we're guessing it's for advanced users only. Translation: We still don't know how it's done.

And as wrong as Miley's might be ... it's still better than Arnold Schwarzenegger's attempt.
