Circle swallow

An egregious effort made in a large group when a guy named Jon, not John, takes a bottle of whiskey and tells everyone to take a pull off of the bottle. He watches the flow of the bottle as it goes down the hatch making sure it’s a pure circle swallow.

Jon: “hey guys, it’s time for a circle swallow.”
Geoff: “get that bottle out of my face. I’ve already circle swallowed 3 times.”
