In any sport in which the object is to hurtle yourself downhill at high speeds (eg Skiing, mountain biking etc.), a gdoink-gdoink is an athletic manoever in which the participant goes into a tumbling motion, sometimes intentional but usually unintentional. The term is derived from the sound one makes while performing this manoever.
Gdoink, gdoink, gdoink!
My skiing holiday ended when I tried the double black diamond. I made 1 turn then went into an amazing gdoink-gdoink. The cast on my leg is great for meeting chicks at the lodge, however.
