Oonch Fancier 

British slang from the 1950s thought to have originated in East Anglia and meaning a lesbian. The word oonch is thought to have derived from the dialect pronunciation of 'conch' and was used as a slang name for the vagina due to the resemblance of the opening of the female genitalia to the opening of a conch shell. Thus a lesbian became an oonch fancier.

"Ah! I wouldn't mind a bit of that!"
"Forget it boy! She's an oonch fancier."
