An acronym for the phrase "Come On You Boys in Green" (C.O.Y.B.I.G.) in reference to a phrase uttered at Republic of Ireland soccer matches in support of our players.
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.
