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"
An extremely high voltage, arguably has the most shockage of all. Do not attempt to in any way interact with it, for you will not be able to survive. A "Shockery" may have a chance to give you electric powers (That's what happened to Geoffrey) but there is a small amount of chance. Anyone who is called a "Shockery" must be awesome in some way, as the voltage would have killed him (As David was killed) Do not underestimate the power of Shockery.
