SWMBO
 n.— «SWMBO. It’s pronounced “swimbo.” While we might be able to take credit for the initialism and pronunciation, the phrase is actually a phrase Idj first heard and read in the John Mortimer series “Rumpole of the Bailey.” In it, Rumpole refers to his wife as “She Who Must Be Obeyed,” and, yes, you can hear the capitalization just as Idj wrote it.» —“Idj’s SWMBO” by Grung SWIMBO (Canberra, Australia) July 1, 2004.
