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.
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.
