    However, this is antedated by usage in horse racing cant that applies the term to horses, and by a US Navy euphemism for drunkenness. The former is attested in Webster New International Dictionary (1909) and the latter in (May 1915). Both may be figurative interpretations of soup as a liquid food item, although other origins cannot be discounted.
