Whooping cough..Violent cough causing the victim to move and heave to clear the chest.....not so much the term but the way it was used by a certain fellow in his description of how it might effect or in his case enhance love making......
Said in response to someone saying thanks. Comes from a Joke where David Hasslehoff asks a Clerk to change his name to the Hoff... when the Clerk said Sure, No Hassle. Now instead of saying "No Hassle" people just say Hoff.
