hot dog horse
n.— «A “sausage horse” would be a derogatory term in Australia, indicating that it is where the animal will end up, but a “hot dog horse” is the opposite. It applied to one always at short odds because of its popularity and which the betting man couldn’t afford to support, thus a snack break was taken when it raced.» —“Our best export? You wouldn’t give a sausage for this ‘hot dog’” by Max Presnell Sydney Morning Herald (Australia) Aug. 5, 2005. (source: Double-Tongued Dictionary)
