Oh; we just called them, "drawers full of crap".
One was usually to be found in the kitchen, next to the sink,
containing all the useless bits of short string, rusty needles,
ribbons, blunt scissors, thread, screws, cheap screwdrivers and

but of a more useable sort. A proper DFoC takes years to accumulate
and has a heritage to it.
