It’s National Dictionary Day. Instead of commanding you all to go forth and look sh*t up, I’m giving you the definition of the last word (term, actually) I looked up.
I do own the second edition of the actual, twenty-volume Oxford English Dictionary (rad dictionary nerds like me call it the OED). I won’t waste my time and yours typing up the long OED definition and linguistic history; we’ll be jumping straight to the weenie, one-volume edition of the Oxford English Dictionary.

Runcible spoon [made famous by The Owl and the Pussycat]:
Noun
A fork curved like a spoon, with three broad prongs, one of which has a sharpened outer edge for cutting.
So, basically what we’re talking about is a fancy spork.
