Footnotes and references
- ↑ Copycat graffiti looks like gang graffiti, and may be the work of gang wanna-bes or youths seeking excitement.
- ↑ Offenders commonly use numbers as code in gang graffiti. A number may represent the corresponding position in the alphabet (e.g., 13 = M, for the Mexican Mafia), or represent a penal or police radio code.
- ↑ Stylized alphabets include bubble letters, block letters, backwards letters, and Old English script.
- ↑ Tagbangers, a derivative of tagging crews and gangs, are characterized by competition with other crews. Thus crossedout tags are features of their graffiti.
- ↑ The single-line writing of a name is usually known as a tag, while slightly more complex tags, including those with two colors or bubble letters, are known as throw-ups.
- ↑ although hard-to-reach surfaces, such as motorway cross-overs might be regarded as attractive challenges
