Stand back 

A phrase used in the sense of "hold onto your hats" Inspired by the 1983 hit by Stevie Nicks, exclaiming stand back once or twice in a row is used to prepare somebody to be shown or told something amazing. The known origins of such use of the term are from around Richmond Virginia, by 80's heads who sought to help keep the 80's alive and well.

Oh my stars! That dude done yelled out "Stand back! Stand Back!" from the bedroom. Next thing he came out dressed like one of the break dancers from the video to that song! He is so retro!

Stand-back-stand-by Math 

When President Trump repealed the “leftish” Common Core Math, approved by President Obama, with zero idea how to replace it with a better “rightish” math curriculum to help millions of US students compete internationally in math—he just wants to pacify opponents of the “left curriculum,” whose children can’t cope with it, in exchange for their votes.

Does the stand-back-stand-by math sound like some curricular or mathematical equivalent of the repeal-and-replace Obamacare? If politics over math could increase the odds of getting the president re-elected, the risks are worth taking.
