Perm-a-grin

Permanent grin. Usually a result of great fortune arriving in someone's life; a brand new love, winning the lottery (or one of my personal fav's: watching someone illegally passing on the shoulder during rush hour and promptly getting NAILED by the cops.)

Look at the perm-a-grin on his face. He is totally twitterpated with her. He smiles all the time, can't stop talking about her, he is always texting or calling her. That boy is whipped!

the fuzzy grin

When a girl with braces gives you head and gets pubes stuck in her brackets

My girlfriend just got braces the other day. She decided to give me head and later on, while talking to her mom, she smiled to reveal a smile full of pubes, the fuzzy grin

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!
