ETYMOLOGY
A made-up word, from hum, gruff, griffin.
EXAMPLE
“… The Demoniac crowd
In an instant seem’d cowed;
Not one of the crew volunteer’d a reply,
All shrunk from the glance of that keen-flashing eye,
Save one horrid Humgruffin, who seem’d by his talk,
And the airs he assumed, to be Cock of the walk,
He quailed not before it, but saucily met it,
And as saucily said, “Don’t you wish you may get it?”…”
