In golf: It's the shot Larry Mize holed from off the green in the 1987 US Masters to deny Greg Norman the title!!

The Blood Eagle was a method of torture and execution that is sometimes mentioned in Norse saga literature. It was performed by cutting the ribs of the victim by the spine, breaking the ribs so they resembled blood-stained wings, and pulling the lungs out. Salt was sprinkled in the wounds. Victims of the method of execution, as mentioned in skaldic poetry and the Norse sagas, are believed to have included King Ælla of Northumbria, Halfdan son of King Haraldr Hárfagri of Norway, King Edmund, King Maelgualai of Munster, and possibly Archbishop Ælfheah of Canterbury. http://en.wikipedia.org/wiki/Blood_eagle
