Acronym for the "United Blood Nation". Though the original "Blood" gang was set up in California, an entirely new sect was started on the east coast (by an "OG Mac"). The UBN is largely rejected by their west coast "brothers" for not following the original codes set by the west coast blood set. Such violations include; the harming of neutrals, blood on blood violence, "sexing" in female bloods, etc. The UBN is widely considered to be less dangerous than their west coast counterparts, and as of now, the internal leadership of the group has mainly fallen apart, making them no more special than any other random street gang.
The UBN is slowly deteriorating under failing leadership

"United Black Network" - Started as UPN in the 1980's, this television channel quickly became a hotspot for crappy, low-budget actors, mostly of whom are bequethed from African American descent, and changed its call letters to UBN to better recognize the targeted audience.
Hey Peter, are you and Jane coming over to watch Sister-Sister tonight on UBN?
