Origin: 1940–45; earlier in form bulldike (with a variant bulldagger); of obscure origin; claimed to be a shortening of morphodyke (variant of morphodite, a reshaping of hermaphrodite), though morphodyke is more likely a blend of morphodite and a pre-existing dyke; other hypothesized connections, such as with diked out or dike “ditch,” are dubious on semantic grounds
1931, Amer.Eng., probably shortening of morphadike, dialectal garbling of hermaphrodite, but bulldyker "engage in lesbian activities" is attested from 1921, and a source from 1896 lists dyke as slang for "the vulva."
n. a lesbian; a bulldiker.(Rude and derogatory.) : Who's the dike in the cowboy boots?
