The sensation you get when you drink a lot of liquid, the tummy becomes "splashy" and can be sloshed at will.

the very center of a persons' abs (more common when it's a 4 pack) that is harder than the rest of that abs, and tightens similar to a knuckle. It hurts when hit directly, similar to the pain of playing bloody knuckles.
(out of stupidity) I'm going to break your tummy knuckle!
My tummy knuckle hurts after doing so many crunches.

Some perverted thing that vanilla people do. You sensually place your hand on the stomach of your lover, hand under their shirt in order to keep the affair private. It is an erotic exchange of tummies and touch.

That part of the day where you get to lie down on your stomach after eating a large and/or satisfying meal. For some, it is the bane of their existence. The best part about tummy time is that it can happen 3 or more times per day!
Person 1: Dude I just ate the meal of my life. It's Tummy Time.
Person 2: What's that, bro?
Person 1: You lay on your tummy and just relax. It's uber therapeutic.
Person 2: Whoa, sounds like heaven. I'm gonna have to start fitting that into my schedule.
