In one podcast I've stumbled upon the following dialog (two hosts discussing new version of software, one of them like it other - not, both of them males):
xxx: Ok, we both have tried that version on that weekend and now lets talk about it. Queens rules?
yyy: Yes.
xxx: The thing that I liked most is...
yyy: But on the other hand...
After that it looks like normal discussion. In that context it sounds like a question which you may ask your opponent just before yours argument/battle. Also I could incorrectly recognize that phrase but it sounds like "Queens rules".
