Smack-mouth 

A condition where your mouth needs to be smacked. This could be because of something stupid you said (1) or simply because you have a tete-a-claques (2).

1. Imagine you are a girl talking to a friend of yours who is a man:

You: Women don't like it when men sit around watching sports and scratching their privates.
Your friend (incredulously): What?
You: No, I'm serious... it's a real turn-off.
Your friend (shrugging): Hmph... either way, it looks like you might have a bit of a case of smack-mouth.
You: What? What's ...?
SMACK!
You: Oh... oh, I guess I do have smack-mouth.

2. Imagine you are standing at the bus stop. A kindly stranger approaches you...

Stranger (pointing at your lip): Excuse me, you seem to have smack-mouth.
You (fumbling with your mouth): Huh? Smack-mouth? What's ...?
SMACK!
You (ruefully): Oh, I guess I do have smack-mouth.

In Mobile, when a couple plays smacky mouth, they are kissing.

Finally I got past simply playing smacky mouth with Gayle.

Sack Mouth

When you suffocate someone using your nutsack. (Picture the way a small child looks when they put a plastic bag over their head and breath in.)

If that bitch/ screaming child doesn't shut up, I'm gonna give her/it sack mouth.
