Smigger

Smigger: noun or verb. A smigger is something between a smile and a snigger. To smigger is to make such an expression. Smiggering tends to occur most in confusing or uncertain contexts, in which it is unclear whether a matter is to be openly smiled at or snidely taunted. One telling use of the word smigger can be found in the semi-contemporary novel (semi-contemporary in the sense that it is a novel written about a long time ago but in an unintentionally anachronistic way) Anne Boleyn and the three dudes, which tells about Anne Boleyn's secret (and probably made up) sexual exploits:

Henry VIII paced the room like a giant bull-frog would if it could not leap.
"So what can you tell me about Henry Norris?" He asked, wound up like a tea-kettle before the little switch with the red light turns off.
Anne grew tense like a verb. She tried to conjure an image of a gallant aristocrat, but her mind was like a TV screen drowning in static. The 'static', of course, was the intruding image of a Henry Norris, naked like a fridge (a fridge without all of the annoying stickers and magnets, that is), with a penis the size of a flash drive.
"Only that he is a great man of great ways," she smiggered.
