The tag was coined in the mid-1990s around the time gang turf battles were ripping Minneapolis apart, bumping local murder rates far past those of cities with more dangerous reputations.

Many of those murders were happening because, in about 1990, three branches from the same family tree founded a gang called the Rolling 30s Bloods. Their territory stretched from I-35 to the west, Chicago Avenue to the east, Lake Street to the north, and 39th Street to the south. (The outfit was not related to the national Bloods gang.)

Once the new crew was established, turf feuds followed on every edge of the territory.
