To win as a result of miraculous circumstances, despite being in a losing position. Especially in the case of sporting triumph. Not to be confused with "homer".

Comes from Australian speed skater Steven Bradbury's win in the 1000m at the 2002 Winter Olympics when every other skater crashed on the last corner.

An improbable victory attained by default; achievement only made possible by the stupidity/clumsiness/misfortune of others.
Etymology: In the 2002 Winter Olympics men's 1000m Speed Skating final, a stumble caused the four leading men to collide in a tangle of arms, legs and blades. Australian Steven Bradbury came from behind and coasted past his fallen competitors to win his country's first ever Winter Olympics gold medal.
