The act of backcountry sledding, during winter, in the woods, usually off trail, and often in the woods, where broken bones are common.
"Man I just went bonzai sledding with a bunch of suocers and I think I bruised my tail bone, and my pants grew a new bogina!"

"That's cool... you need a beer?"

"Yeah. Thanks."
