Definition: "Did you know that 'tumphy' was once a popular term for someone who has too much energy and no energy at all? Imagine this guy: he's always on the go, but when he gets tired, it's like his entire body is on fire! And that's just one example of how 'tumphy' can make your brain melt. He's full of energy, but all you need to do is call him a 'tumphy' to give him a jolt and put some serious pressure in!"
