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

Man, watch your teeth. I don't approve of that word that begins with an "N."
