Basically it means The Bay Is Back. I know some of my folks from tha Town dont know and my Frisco folks get it twisted all the time so I gotta break it down. It's almost like a commercial acronym that got the streets challenged to solve the puzzle. Often it's used when ultra cool people take notice of a refference/acknowledgement towards the Bay Area.
