DBM stands for Dope Boy Mafia (hip-hop group/label). A MySpace tag reads them DBM niggaz is hot! This organization is based out of ATL (Atlanta GA), LA California, and DYT (Dayton OH). DBM members have a hand gesture that is easy to execute (point index finger down towards the palm and hold hand out). It can also be reasonably assumed that DBM members have ties with the Black Mafia Family (BMF) since DBM members have been seen wearing BMF jewelry and BMF clothing. Likewise, it is also reasonable to assume that DBM members use the hip-hop music and entertainment label as a cover to launder drug money.
Known DBM members include: Reddy Baby, Nutts, 6'8", Lil Chris aka Ca$htro, and DBoy.
