Wikipedia Talk:List of medical abbreviations Early threads I believe an acronym arising as an abbreviation is still an abbreviation. At any rate, the word "posh" did not arise as an abbreviation or acronym for "Port Outward Starboard Home". You might do better with SCUBA, which really does stand for "Self Contained Underwater Breathing Apparatus." -Dan Hoey 23:20, 8 April 2007 (UTC)
