Stacked

Faceplanted, fell, biffed, beefed, eaten shit. A person who has stacked has fully, bodily fallen all the way down, completely off of their feet. Always involves pain, usually accompanied by injury whether great or small, to stack is to hit the ground with your body, and without intention, so it necessarily hurts. A faceplant is always a stack, not every stack is a faceplant, thankfully. This was common usage in skate culture in Northern California Bay Area in the 1980s, still used frequently by surviving GenX of that area, we have passed it on to our children. Probably came about by watching our friends fly off of their skateboards perpendicular to the ground so when they hit, it stacked their body onto the asphalt or concrete. I can't believe this isn't already here.
