Gray Magic 

The type of magic performed when a white witch breaks temporarily with her "do no harm" rede and does a little black magic when she's pissed off.

The man I fell for online turns out to be a scammer that's asking me for money. I think I'll break out the voodoo doll and do a little gray magic tonight.

Gramagical 

A term used when someone makes a Grammar Fail while talking or typing. Usually something that someone says that is obviously incorrect, or out of order. Used as Sarcasm.

Me: Mearna carries everyone that has glomped to Kiba and glomps on Kiba.
Someone: Wow, that was... Gramagical.
