When you make a gesture or movement that is highly powerful, fierce, and effective.
OR When you are stirring up drama “causing a rumbuckis”
A fierce gesture or motion such as moving a cart onto a curb with force, or moving fast and recklessly breaking something.
OR coming into a party hot while in a sweaty rage and roasting everyone there while poorly shotgunning a beer and failing to apologize while running away and not saying sorry.
“Woah dude! Kyle really did cause a rumbuckis at my rager.”
