I really dont have any rules because usually I would be smokin with them lol I never have anyone smoke over my house and if I go over my friends house to smoke usually I have my own blunt and they can smoke theirs. But I hear (and saw) in California if you fuck up the rotation you get punched in your face. I didnt see it up close but I seen it on "Ghetto Brawls", lol the guy took like 5 hits and got punched in the face.
