"Off limits" describes a place where you are not allowed to go. Example: "The park is off limits; I do not want you going in there." Children like to forget where they're not supposed to go, so parents often remind them which places are off limits. Example: "When you are wearing muddy shoes: the house is off limits!" Example: "Don't let the dog go into the kitchen: It's off limits to him." You can use "off limits" in creative ways when place limits on what people can do: "I don't want you dating high school boys; you are too young and they are off limits." Example: "Guns are off limits within New York City."
