beaver-eater
noun a person who performs oral sex on a woman. In a brilliant sexually charged pun, Vladamir Nabokov in
Lolita wrote of 'the Palace Sentries, or Scarlet Guards, or Beaver Eaters, or whatever they are called', creating misdirected confusion with 'Beef Eaters' but leaving no doubt as to the sexual nature of his malapropism
