If you are on the receiving end of obloquy, then society has turned against you and you are in a state of disgrace. Poor Hester Prynne who was forced to wear a red "A" on her chest for "adultery" knows all about obloquy.
If you break the word obloquy into its two Latin roots, you have ob, meaning “against” and loqui, meaning "to speak" — so obloquy means “to speak against," in an especially mean way. Obloquy can also be the result of public shame, or criticism. Sometimes obloquy takes the form of offensive or rude language: "It's not easy, but I've found it's best to ignore my sister's obloquy when I beat her in Monopoly."
