A GT Snowracer is a sex move where you are banging a girl doggystyle at the top of a staircase. One large thrust sends the two of you sledding down the stairs where you quickly pull out, ejaculate over her head and into her face (like snow). You position yourself on top of her with your hands pulling her arms back for steering. You bail at the bottom of the stairs as she skids out the front door.
