Taylor Swift is famous for dancing like nobody's watching during award shows, and this week, she satisfied a fan's request to define one of her moves. Somebody on Tumblr posted a GIF of Taylor dancing and singing along at this year's Grammy Awards, and the pop star replied after one fan wrote, "Taylor this is so important, we need a name for this move." Here's her perfectly on-point response [1]:

The Mom-Croon - (noun) A dance move invented at the 2014 Grammy Awards. 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. Cynics may judge the Mom-Crooners (MC's as they are commonly referred to in the dance world) as it is a form of dance only perfected by those willing to be absolutely swept away by the feels you get when you hear a certain song. Those who know how to Mom Croon cannot see the eye rolls of haters. They have reached a level of musical transcendence that is hater-proof. Once you perfect the mom croon, you are truly free.

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. Oh God. Now she's crying."
