California has two different statutes prohibiting “annoying”, one for “annoying” a child, and one for “annoying” anyone by telephone.

CA Penal Code § 647.6:

(a)(1)?Every person who annoys or molests any child under 18 years of age shall be punished by a fine not exceeding five thousand dollars ($5,000), by imprisonment in a county jail not exceeding one year, or by both the fine and imprisonment.

CA courts have required specific intent motivated by unnatural or abnormal sexual interest in the child, plus three more elements. So telling a child “Get off my lawn” can’t be prosecuted even if doing so annoys the child.

CA Penal Code § 653m prohibits phone calls intended to annoy any person. But the statute limits itself to threats of injury to person or property, obscene language, and repeated phone calls intended to annoy. The meaning of “annoy” is not left to the discretion of the called party.

So, I think Prof. Volokh would find both those “annoying” statutes constitutional, with perhaps some question about what constitutes “obscene” language.
