Mud mouth 

When you've been out in the desert so long that you accumulate mud in the corners of your mouth caused by dirt accumulation and sweat.

You've got some pretty serious mud mouth going on man. We should probably go home.

Not in the mouth 

Used awkwardly -- and ONLY awkwardly -- after something you've said to/about the opposite sex (or same, if that's how you go about) could be mistakenly taken into a flirtatious or more-than-friendly context. Replaces "but not like that" in most cases.

Basically:
"I'm completely positive towards you at the moment, but not in a way that I want to shove my crotch into your face."

Dude 1: Yo, do you like her?
Dude 2: Yeah . . . but not in the mouth.
Dude 1: What the HELL does that MEAN?

Heaven in my mouth 

1. When something tastes so OVER-THE-TOP delicious, that it can only be compared to heaven (in your mouth of course).

2. Can also be used seductively while eating delicious food as a double entendre to imply that you are good at giving head and that if you were to perform fellatio on a certain someone it would be heaven for him (in your mouth).

1. "Mmmmmm....This mac and cheese is like heaven in my mouth!"

2. Girl: "Mmmmmm... This ice cream cake is heaven in my mouth!"
Guy: *gets an erection*
