Finishing up our month of fools, we come to the slang term I’ve easily incorporated into my everyday speech. A child up to no good will smile madly in effort to distract you from discovering the new worm habitat in his bedroom.
Also known as The Cat’s Uncle. A foolish grinning fellow, one who grins without reason.
To use more cant, a Grinagog will use his or her grinders (teeth) to full effect.
And there’s nothing like the grin of silly fools in full flirt.
Slang term taken from 1811 Dictionary of the Vulgar Tongue.
