We don't have a system like this in CF culture, and we certainly don't want one. Breaking character is just that... breaking character, and by definition isn't roleplaying. Any OOC speaking is likely to result in, at best, a pray to the immortals asking someone to explain to you why you can't do that.

That being said, it isn't uncommon to hear unavoidably OOC things explained in as best an IC manner as possible. For example, if you have to go afk, it's common to hear "My mind wanders a moment" or "My attention wanders" or something else similar, that I suppose might be consider OOC information blanketed with roleplay. You'll also commonly hear "I have to rest" or "Return to my prayers" or "Take to my hut" or any number of phrases that mean "I have to quit!".

I can't really think of anything that you couldn't coordinate just fine in-character. Did you have a specific example in mind?
