facedropping
When you're doing something fast and you crash face-first into the ground. Like you’re a kid who forgot to watch where they were going.
I was biking and ran into a tree. My face went into the dirt. It was messy.
I was running and tripped over a rock. My face hit the ground like a pancake.
I was skiing and went off the slope. I flew face-first into the snow. I looked like a snowman.
