Bonkbuster in OED
Among the new additions to the Oxford English Dictionary:
Bonkbuster, n. Chiefly Brit. (colloq and humorous). A type of popular novel characterised by frequent sexual encounters between the characters.
The Guardian cites Jackie Collins, Harold Robbins and Jilly Cooper as prime examples of "bonkbuster" authors. The paper also gloats that the term originated in its pages. Columnist Sue Limb, who wrote the Guardian's humorous "Bad Housekeeping" column under the pseudonym Dulcie Domum, coined the term after a publisher asked if she could write "a big, thick book with lots of bonking in it."
