bloody noun

Etymology
From "blood 'n' 'oun's", from "blood and wounds". Several sources, including Harrison Garman's 1892 A Synopsis of the Reptiles and Amphibians of Illinois, say the frog is so called because "its peculiar bass notes have a fancied resemblance to the expression" blood and wounds and other similar-sounding and similarly imposing phrases like "be drowned".
