Invented word edition! Because I come from a cluttery and packratty folk, I find a lot of use for clutter words, such as the slightly fear-inducing ‘kipple’ invented by P.K. Dick. But here’s another neologism of decades’ standing, which has much currency in my family:

…anything that Hobbits had no immediate use for, but were unwilling to throw away, they called a mathom. Their dwellings were apt to become rather crowded with mathoms, and many of the presents that passed from hand to hand were of that sort.
Prologue, The Ring Sets Out, The Lord of the Rings

J.R.R. Tolkien and P.K. Dick have my number entirely. Mathoms and kipple, alive, alive-o.
