A poor excuse for a dance move designed in thirty seconds, in which you wiggle your ass back and forth like there's a three foot dildo in there, and then walk forward and backward stiffly. (Imagine walking while holding a shit)
"Yo did you see Emily last night? she does the butt stuff shuffle a tad too well"
One who creates a feeling of discomfort and strife leading to irritation and annoyance which can translate to a physical response of the tightening of your sphincter.
“Ugh Tom was being such a buttscuffle during the meeting when he kept arguing everyone’s point.”
“The HOA meeting, turned out to be nothing but a buttscuffle”
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
