rock and cock

From the television show Cops:

Woman talking to a police officer. She says she gave $20 to her neighbor to buy something and her neighbor didn't buy it. Now, she wants her money back.

The police officer asks the woman what she asked her neighbor to buy. She wouldn't say. When pressed, she says, "Rock." Crack cocaine. She says her neighbor gave her plaster instead.

Police officer goes to talk to the neighbor. Neighbor is indignant and says, she came around and said give me my $20 back, give me my $20 back. "Don't come disrespecting my house. This is my house. My child is here. I don't sell crack. I'm a prostitute!"
