From Rap Dictionary
The L.A brims are a set of three different gangs in Northern South Central, Los Angeles, California. These gangs were started in the 1960's by various young African-Americans. In 1972, the L.A Brims took part in a large meeting that led to the formation of the Bloods, Since then, no L.A Brim gang has ever had a rivalry with another Bloods set, and have adapted to wearing the color red. Major allies include the Rollin 20s NeighborHood Blood, and Crenshaw Mafia Gang Bloods.
