In Gulf Arabic it stands for "outstanding," "masterly," In Nejdi Arabic the name stands for a place travellers gathered before leaving, so that's way it called Al-mubarraz because the people get to it before their trips. The sheikh Muhammad Alabdulaqader write that the people of Al-Ahsa gather there first before leaving for Al-hajj. so it's agreed between almost all Al-mubarraz people. This last, however, seems like a folk etymology and folklore than reality.
