Is there a name for phrases (or sometimes words) that have lost their previous specific/narrow/jargon meanings and are now used generally in a wide variety of situations with little or no knowledge about their prior usage? Are there lists of them anywhere with the phrases and explanations? [more inside]
Where did the phrase "the shit hit the fan" originate from? My googling has revealed one claim that it is from 1930's jazz lingo, although no explanantion is given as to what it meant at the time, and another site gives a story that describes the origin that doesn't seem believable. (the last paragraph here: http://www.etymonline.com/index.php?term=shit Does anyone know where the phrase came from? Thanks!
