a person who is so much of a bitch, that they actually physically turn into a cock shaped sponge. this sponge man/woman can be used to scrub your genitals in a clockwise motion until ultimate satisfaction. the cocksponge is a very rare species, and usually very dirty as well. they enjoy long walks on the beach, romantic dinners and vigorous genital massaging daily.
Nigel Hamflick elavated his bitch status just enough to transmutate into cocksponge form. he was then condemned to a lifetime of genital cleansing sessions with president bush himself.
