I'm sorry to be such a buzzkill on this topic since so many seem to be complimenting it but half of these terms I've never even heard of and seeing that I was mentored by several decade or longer roleplayers (meaning yes they've been roleplaying and gained amazing experience for ten years or more), that's saying something.
Meta gaming, god modding and auto hit are essentially right although definitions of them vary from who you ask and can have multiple definitions. These other terms..just seem made up to me. It's like the new use of 'bunnies' to describe beginner roleplayers. It's a made up term by someone who wanted to start a new trend when there are pre-existing words that describe the situations perfectly fine.
If you really want to set up a guide, stick to the basics first since that's what seems to be lacking the most in Feral Heart. Basic terms such as out of character, in character, canon characters, head canon, god modding, power playing, 'literate' (which is in fact utilized so incorrectly it's beyond ridiculous), Mary Sue, auto hit, roleplay, original character and more. There's a ton more to the simplified format of roleplay and the messed up idea of having to use the biggest words possible to seem like the most experienced player out there. Ask any veteran roleplayer or retired or even venture out of the walls of Feral Heart and see what I'm talking about.
All in all, the list is incomplete and requires some extreme revisions. Please make sure you post things that are thought through to their fullest before posting them that way the beginners of this game won't learn wrong and have to be (if even given the chance) retaught how to roleplay.
