This is American junior wrestler Ellis Coleman performing an insane, flipping Greco-Roman wrestling move called "the flying squirrel" at the junior world championships:
It's hard to decide which part is best: how fluidly Coleman leaps, grabs, lands and performs a two-pronged takedown or that his lack of expression afterward suggests that doing all of those things was as routine as crossing the street. The flying squirrel is cool. Acting like doing the flying squirrel isn't cooler makes it even cooler.
It's hard to imagine this will become a go-to move in Coleman's wrestling arsenal though. The flying squirrel seems to rely on the element of surprise. If an opponent is expecting the maneuver, it wouldn't end well.
Coleman would go on to win the bronze medal in the event.
