Question: what is the baby shark thing with the washington nationals?
Answer: The Nationals players also use "Baby Shark" gestures when they get a base hit. A single merits the finger pinch of the Baby Shark, a double gets the hand-clapping of a Mommy Shark, and a triple means a two-armed chomp gesture for Daddy Shark. And a home run? That means a full-on dance party in the dugout.
