omnium-gatherum \ahm-nee-um-GA-thuh-rum\ noun
Meaning: a miscellaneous collection (as of things or persons)

Mr Mayhew's bag was full of nothing, a huge omnium-gatherum of useless objects and ephemera, the likes of which you could pick up in a charity shop for ten pence a piece. He had never meant to have so much, but couldn't stop himself buying things. Everything individually was a beauty to him, though together he saw they were a confusing mess. The truth was that ever since his wife had died, Mr Mayhew was not entirely sure how he was getting from one moment to the next. Everything seemed to be an impulse, and each impulse seemed irreconcilable the moment after it had happened.
