grin from hell

huge smile that simply will not go away, despite obvious facial muscle fatigue.

You've just spent all day in a Porsche, at the racetrack, with a professional driver coaching you around. It's 11PM now, you're in the hotel room, unable to sleep because your jaw hurts so much from the grin from hell you're stuck with now.

Grin yuh bam bam

A grade above mooning - a vulgar motion where you show disdain for someone by revealing your backside and spreading your buttocks.

"The man was so upset his friend told him to just grin yuh bam bam."

carpet grin

When a cat opens it's mouth drawing air in and up into the Jacobson's organ to process the scent more deeply than your cat's nose can. Usually resulting in an open mouth grinning expression.

"What's on this blanket? The cats got a wicked carpet grin."
"Dale, the damn cat is grinning at the carpet again!"

Shennani-grins

Sneaky and chaotic fun that is intended to brighten other people's day, but does no harm and is at no one's expense.

Anyone up for shennani-grins? We should go do some google-fiti downtown and try to help people smile. Maybe we can find a beer cock to decorate!
