This newly formed phrase is missing.

'He has went' and 'it don't matter' drive me crazier than usual.  Now, used by even the most eminent newscasters is a two worded phrase.  I will type it for you but if there's a two minute pause, please excuse me.  It depends on how badly I gag as I write it.  What makes this phrase even worse, it replaces just one word where now two are required.  The sense of it is beyond me.  Ready?  16 people 'went missing' after going for a hike in the wilderness.  Or one, or two, it doesn't matter.  They all 'went missing'...Sigh.  For now I shall 'disappear'.......................marge
