While the nae nae's hijacked most United States dance floors, Taylor Swift is content to cut a rug with her signature frantic marionette moves—and now they've got a name.

Tumblr

In a recent Tumblr post, SwiftiesinFundon posted the GIF above of one of the 1989 singer's most infamous moves and asked what, exactly, it was. Finally ready to share the secrets to her art, T. Swift bore her soul, and officially deemed the step the "Mom-Croon."

"The Mom-Croon—(noun) A dance move invented at the 2014 Grammy Awards," she began. "To sway, perform, and sing along to a song in an extremely emotional or sentimental way, possibly incorporating hand gestures. Eyes closed, lost in the music. The way your mom gets taken away by a tune from her high school days, glass of red wine in hand, shuffling around the room as her teenage kids roll their eyes in disdain...Once you perfect the mom croon, you are truly free."

IF ONLY WE COULD HAVE IT USED IN A SENTENCE, THOUGH, FOR SPELLING BEES.

"Used in a sentence: 'Oh look, Taylor’s being embarrassing again—just mom-crooning away in the corner by herself because 'Sometimes' by Britney Spears came on,'" she continued. "Oh God. Now she’s crying.”

Reports say—for better or worse—Swift will continue to dance like nobody's watching.
