Red Baron Mouth 

The pain and sensitive rawness of one's mouth for a day or two, after eating a frozen pizza too quickly after leaving the oven. Leaving your mouth singed from the molten cheese and tomato sauce.

My case of Red Baron mouth made to eat anything salty the next day, I really should have waited a few more minutes to start eating that frozen pizza.

spitty mouth 

The sensation one feels when their mouth begins to salivate and fill with spit, after having had too much to drink. This is then usually followed by vomiting, however some can fight it off. Either way, you'll be spittin'.

Bro #1: "Yo dude, take down that shot!"

Bro #2: "Can't do it man, I've got spitty mouth."

Mouth gape 

The permanent slight opening of the mouth due to being overstretched usually by multiple dicks.

I decided to push the limits of the suck fest by wanting a third dick added to my mouth once that happened I felt my mouth stretch. Oh great, I ended up with mouth gape. Now I can't stop drooling.

Watch your mouth

this verbal warning and boundary is provided when someone takes personal offense to what someone else is saying. It is meant to urge the person to reconsider what they are saying.

The term can be followed up with an “or else” but it is usually the final warning before a consequence is given (a slap, getting blocked, etc.)

Ann: People from Chicago are lazy, stupid, and unconcerned.

Vance: Uh, I’m from Chicago.

Ann: So?

Vance: So Watch your mouth
