A prostitute, specifically one fulfilling their role in an Executive Round. This occurs when 18 holes of golf are following by drinks at a local bar(19th hole)and then by a sexual frolic with a professional.
Pardon the limp, I suffered a major calf cramp at the 20th hole on Sunday and it has been knotted up since.
