The situation is like this. A girl named Letitia was about to buy a house with atrium, but she found a naked divinity statue of Hecate, a goddess of the moon (it could be guessed because there was a crescent moon shaped tiara in her hair) in the center of the atrium. Letitia who didn't like this centerpiece because of the obsceneness, circled around to the statue’s rear and said this.
“I see the moon all right.”
At first, I thought the moon refers to the slang word for naked buttocks but I'm not sure about it because Letitia said 'the moon' not 'moons'.
Can the moon be used to say the buttocks?
