The Five Eight Rule is a rule in relationships between expatriates and locals of a host country. An expat or local who is considered a "5s" by their own home dating market is viewed as "8s" by the opposite party. Often, the rule applies to both parties. Each one perceive the other as an "8", but they are both, in reality, "5s" in their own home dating market.
