This is my life

I would say, instead of "No OOC", to specify what is OOC for you. If non-canon nicknames drive you up the wall ("Hey, honey-bunny*," John called to Rodney), or if you can't stand characters whining/crying/giggling/tittering, or if you simply cannot wrap your head around Dom!Keller or pushy bottom!Lorne or amoral!Sam, these are things even bad writers can work with.

* IRL busaikko calls everyone either honey-bunny, darling, sweetheart, or love. I'm totally down with nicknames, personally.
