Ooh, SNAP, Shakespeare!

And who, you no doubt asked yourself this morning upon rising, could have coined the term "indigested"? It's a lovely adjective, derived from the participle of the verb, eh?

Well, ask yourself no longer; the answer is here: SHAKE-SPEARE, of course! And, furthermore, he used it as part of an insult, ha ha! Unsurprising.

The OED gives this earliest written usage:

1593 SHAKES. 2 Hen. VI, V. i. 157 Hence heape of wrath, foule indigested lumpe, As crooked in thy manners, as thy shape.

I'm totally gonna call somebody a "foul indigested lump" the next time I get cut off in traffic. Fer reals.
