When you smoke some really good medical cannabis and get aroused.

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!

Permagrin 

A long lasting smile usually caused by the frivolous feel after a great session of sex. A great partner is required to achieve this higher plane of sexual satisfaction. Accompanies lightheadedness, temporary speech impendiment, being off balance, carelessness, blurred vision, and general sexual "outbursts"

He walked into the room with her, after five hours they both walked out stumbling with empty eyes and permagrins plastered to their faces.

permagrin 

1) a blissfully wide post-coital grin indicative of particularly satisfying sex. usually indicates a strong sense of emotional closeness with the partner responsible for said sex. permagrin derrived from sex can often last for an entire day. this phenomenon is primarily experienced by females, but under certain circumstances can be found in males for the same reason.

2) a blank, complacent smile experienced after smoking an especially copious ammount of marijuana. permagrin will often fade once the initial high tapers off a bit, and the smoker regains cognitive abilities.

3) the blank, starry eyed grin which acompanies the ingestion of psychedelics. this type of permagrin typically occurs while observing something particularly prone to producing hallucinations, such as a moving light or toy.

1)Kim: "Wow... you've got permagrin. Have a good night?"
Jane: "Yep. Ten back to back orgasms. I love Reggie..."

2) Mike: "Heh... looks like those brownies are kicking in. Kev's totally got permagrin..."

3) Rich: "Is Raul tripping? He's been staring at that mirror for fifteen minutes with this permagrin on his face the entire time."

Permagrin 

A long-lasting, most likely goofy looking smile that does not go away for an extended period of time. This most likely happens when surrounded by awesome company, and great music in the middle of the ocean or on a tropical island.

The outward expression of absolute bliss.

Julie had permagrin the entire time she was rocking on the 311 Cruise ship!

Just the thought of the 311 cruise gives Julie permagrin!

A really bad headache that lasts for many days at a time, sometimes up to a week. It may return later as triggered by a loud noise, an obnoxious person on the subway, or a phone that won't stop ringing.
