"Attempting to force an angry frown through a shit-eating grin, and failing miserably."

From verb "frin": frown attempt overruled by amusement

Origin: I received "frinning" as a typo and knew it was just too good a word to waste. The writer was a dear friend who made a lot of typos, which sometimes became exasperating but were often funny, and I realized I was, at that very moment, frinning myself.
