of the Bloods, as the sign reads the word "blood" Bloods members identify themselves through various indicators, such as colors, clothing, symbols, tattoos, jewelry, graffiti, language, and hand signs. The Bloods' gang color is red. They like to wear sports clothing, including jackets that show their gang color. The most commonly used Bloods symbols include the number "5", the five-pointed star, and the five-pointed crown. 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. 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. Such graffiti can include gang names, nicknames, declaration of loyalty, threats against rival gangs, or descriptions of criminal acts in which the gang has been involved. Bloods graffiti can include rival gang symbols (especially those of the Crips) drawn upside down. This is meant as an insult to the rival group and its symbols. Bloods members also have a distinctive
slang. Members greet each other using the word "Blood" and often avoid using words with the letter "C", or cross it out. Bloods use hand signs to communicate with one another. 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. 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. Other UBN symbols include a bulldog and a bull. ==Sets==
