Okay, so as not to start a new thread, I'll just add my two favorite athlete related obscene gestures of sporting history. This one above has garnered so much attention, and it is physically impressive, but i think it rates kind of low in the grand scheme of things.
Best gesture from a losing athlete: Think this ebay listing actually has an authentic autograph? https://www.ebay.com/itm/225794695690
Awesome because he's flipping off the yankees, obviously.
Best overall: https://en.wikipedia.org/wiki/Władysław_Kozakiewicz#Olympic_gold_and_Kozakiewicz's_gesture
in Poland, they apparently re-named the gesture in honor of this specific salute he gave to the russian crowd in 1980.
