fractious (adjective) 

Fractious (FRAK-shus) means quarrelsome; irritable. As used in a recent article in The Economist about the debate, in China, over whether a 14-year-old girl was a victim of rape by her wealthy guardian or a willing partner: “Bored and fractious after weeks of quarantine, many have followed the case eagerly. With each twist in the tale, the public mood has swung.”
