stay hitched = ?

stay married.

Working horse teams are said to be hitched together, when the reins and traces and all that stuff whose names I don't know are put on them so that they can all pull together, to draw a wagon or a carriage or a freight dray or a stagecoach. The knots in ropes that hold things together so you can carry them also have names like "half hitch" or "clove hitch", which you learn to tie in Boy Scouts. By analogy, when you get married and are supposed to be working together, you're said to be "hitched"--that's probably a century or two old as slang, probably used more rarely today than it used to be, since we don't really use horse teams much anymore.

Thank you both
