(c) “Adult cabaret” means an establishment where a dancer or other entertainer provides live adult entertainment, expositions, or shows, including but not limited to floor shows, exotic dancing, male or female impersonators, or similar entertainment and engages in a private performance, acts as a private model, displays or exposes any specified anatomical area(s) to a patron or customer, or wears or displays to a customer any covering, tape, pastie, or other device which simulates or gives the appearance of the display or exposure of any specified anatomical area(s).

(q) “Specified anatomical areas” means:
1. Less than completely and opaquely covered:
a. Human genitals, pubic region; or
b. Showing the areola or nipple of a female breast.

2. Human male genitals in a discernible turgid state, even if opaquely covered.

(r) “Specified sexual activities” means simulated or actual:
1. Showing of human genitals in a state of sexual stimulation or arousal;

3. Fondling or erotic touching of human genitals, pubic region, or areola or nipple of a female breast.
