Eat your kneecaps
When you hit the ground so hard your knees are gone and you swear you're going to eat the person who made you fall.
He landed so hard his knees turned into soup and he shouted 'I ate your kneecaps!' at the sky.
She fell from a mountain and yelled 'I ate your kneecaps!' like she was eating a taco.
He crashed into the floor and said 'You just got kneecapped by my knees.'
