The state of being so happy or content with the world and your life you spontaneously drum your own tummy
Your favorite sports team just won the world series so you and your mates go in to a bout of tummy drumming

The act of slapping your dick on your stomach before/after masturbating. To grab it at the base and swing it towards your stomach to produce a slapping sound.
When I was getting warmed up to fap last night, I did a Tummy Drum Dong Solo just to get more in the mood.
