Dab dance
The Dab is when you bend your elbow like you're trying to escape a bear and stick your other arm up like you're king of the world. It's not for the weak, and if you do it wrong, you'll look like a confused robot.
I did the Dab at my dad’s wedding and interrupted the vows.
My brother tried the Dab in the grocery store and bumped into a shopping cart.
My goldfish does the Dab every time I feed it.
