Once released from prison, UBN leaders went back to their New York neighborhoods, where they retained the Bloods name and started recruiting members.
Many of the non-Crip gangs used to call one another “blood”.
 Membership Bloods are a loosely structured association of smaller street gangs, known as “sets”, that have a common gang culture.
These symbols are meant to show the Bloods’ affiliation with the People Nation, a large coalition of affiliates created to protect alliance members in federal and state prison.
“Associates” are not full members, but identify with the gang and take part in various criminal activities.
 United Blood Nation Main article: United Blood Nation “Bloods” is a universal term used to refer to West Coast Bloods and United Blood Nation (UBN, also known as the
East Coast Bloods).
 Blood sets have a loose structure of ranks based on how long a person has been involved with a particular set.
To the extent that women belong to the gang, they are usually associates and tend to be used by their male counterparts to carry weapons, hold drugs, or prostitute themselves
to make money for their set.
UBN started in 1993 in Rikers Island’s George Motchan Detention Center (GMDC) to form protection from the Latin Kings and Ñetas who were targeting African-American gang members.
United Blood Nation (UBN) or East Coast Bloods initiates often receive a dog paw mark, represented by three dots often burned with a cigarette, on their right shoulder.
The most commonly used Bloods symbols include the number “5”, the five-pointed star, and the five-pointed crown.
The majority of set members are called “soldiers”, who are typically 16 to 22.
The Bloods comprise various subgroups known as “sets”, among which significant differences exist, such as colors, clothing, operations, and political ideas that may be in
open conflict with each other.
A leader, typically an older member with a more extensive criminal background, runs each set.
These two groups are traditionally distinct, but both call themselves “Bloods”.
Several non-Crips gangs formed during this period were no match for the Crips and became concerned with the escalating Crip attacks.
Hand signs may be a singular movement, like the American Sign Language letter “B”, or a series of movements using one or both hands for more complex phrases.
Several gangs that felt victimized by the Crips joined the Pirus to create a new federation of non-Crips neighborhoods.
These symbols may be seen in the tattoos, jewelry, and clothing gang members wear as well as the gang graffiti with which Bloods mark their territory.
