Some do it after they score the winning shot (ala Michael Jordan), others do it after they hit a home run, and for the local flavor... some do it after they score a goal.
David does it after he eats something he considers, "yummy". Thanks to Grandpa Toh, David's latest gesture is the "Yummy Fist Pump".
Above he demonstrates after eating a bit of cheese.
"Is it yummy, David? Is it yummy?" someone asks.
David's reply is usually then, fist pump - fist pump - and then a big grin.
