When a skier or snowboarder is hiking the boot pack or traversing a ski slope while wearing a backpack and the person behind them pushes the off into the deep snow.

I Turtled em into the powder and the poor bastard was left there floundering with his arms and legs flailing like a turtle on his back.
Jason pushed that dude off the boot pack and turtled em into 3' feet of fresh pow.
