To take a large and steaming shit of a massive contiguous shape. Generally outside in the cold (I.E. camping, wintery situations, etc). Can envoke a dragon like roar/howl to express pure glee and accomplishment.
Oh man, I have to drop the dragon something fierce!
Dude, I just dropped the dragon over behind that tree(perhaps you heard my roar?). Be careful over there, it is still breathing fire! (hence the rising steam)
