The Great Gatsby, racy pasquinade

Could you please tell me the meaning of "racy pasquinade" in the last chapter of The Great Gatsby?

Most of those reports were a nightmare—grotesque, circumstantial, eager and untrue. When Michaelis's testimony at the inquest brought to light Wilson's suspicions of his wife I thought the whole tale would shortly be served up in racy pasquinade—but Catherine, who might have said anything, didn't say a word.

Thank you.
