A subset of spousal abuse, involving the wife smacking the crap out of her man, usually for saying something that she'd already warned him not to say or as an escalation of a hissy fit.
Woman1: "I haven't seen your friend around lately, WTF?"
Woman2: "She's serving 8 months for man smackery."
Woman1: "Her man said 'whatever' again, didn't he?"
Woman2: "Mmmm Hmmm"
