Human Tabloid
A person who primarily derives pleasure from acquiring and then spreading private, sensitive, and potentially harmful information about other people. Such activities are typically their primary form of entertainment, and they usually justify their behavior by pointing out how common and "normal" it is.
My neighbor is basically a human tabloid. Every time I speak to her, she is always so damn eager to share sensitive personal information (juicy gossip) about other people, while simultaneously trying to nose her way into my own affairs, no doubt intending to spread my own dirt far and wide as well. Usually, she feigns genuine concern, but she is obviously solely motivated by the prospect of entertaining herself, because at no point does she use the information she gains to actually help anybody. What a bitch. Human tabloids like her are everywhere, so you gotta stay on your toes.
