Social clubs on United States Air Force installations were at one time called Open Messes, even though most were known in vernacular as Officers Clubs or NCO clubs. Those for officers were able to utilize their initials as colorful acronyms, among the more well-known of which in the 1960s and 1970s were Zaragosa and Zweibrücken (ZOOM), Danang (DOOM), Ramstein (ROOM), and Korat Air Bases or Kirtland Air Force Base (KABOOM), Randolph AFB (Auger Inn) and Nellis AFB (Robin's Nest), with the nicknames usually ascribed to those facilities' casual bars versus the entire club.
