N.J.S.A 2C:33-2 defines disorderly conduct as either:
a. Improper behavior. A person is guilty of a petty disorderly persons offense, if with purpose to cause public inconvenience, annoyance or alarm, or recklessly creating a risk thereof he
(1) Engages in fighting or threatening, or in violent or tumultuous behavior; or
(2) Creates a hazardous or physically dangerous condition by any act which serves no legitimate purpose of the actor.
b. Offensive language. A person is guilty of a petty disorderly persons offense if, in a public place, and with purpose to offend the sensibilities of a hearer or in reckless disregard of the probability of so doing, he addresses unreasonably loud and offensively coarse or abusive language, given the circumstances of the person present and the setting of the utterance, to any person present.
