mouth boner

A shit eating uncontrollable grin. It is best explained by the guy in the Disarono commercial after seeing the chick deep throat the ice cube.

Did you see the mouth boner on Brent's face when he was watching the Jude Law movie?

Mouth boner

That tingly feeling you get in your mouth when you think of a certain food or start eating something you've been thinking about eating.

Person 1: Why did my mouth feel weird when I took a bite of that Thin Mint?
Person 2: Dude that's a mouth boner

An insanely delicious meal. Craving a particular food for a long time and finally getting it.

"I'm dying for a good Philly cheese steak. One if those is giving me a total mouth boner"
"Yo somebody's getting some liquid diarrhea tonight."

"Wow, that girl at the gangbang audition was a real boner-mouth!"
