Key Terms in Street Art & Graffiti

Tag
A quick, stylized signature created with a marker or spray can. It is the most basic form of graffiti writing and often serves as an artist's identifier.

Throw-up
A more elaborate version of a tag, usually bubble-style letters filled with one color and outlined with another. Faster to execute than a full piece.

Piece (Masterpiece)
A complex, large-scale graffiti artwork, often incorporating advanced lettering, color blends, and background elements.

Stencil
A technique in which an artist cuts a design into a sheet (paper, cardboard, plastic, etc.) and sprays paint through it to create precise, repeatable images.

Paste-up / Wheatpaste
A printed or hand-drawn artwork adhered to a wall using wheatpaste glue, commonly used for posters, illustrations, and political messages.

Mural
A large-scale painting executed on a wall, often commissioned and sometimes legal. In street art, murals allow for detailed, conceptual works.

Techniques & Materials Vocabulary

Aerosol Paint
Spray paint used by graffiti writers and street artists. Known for quick drying time, versatility, and ability to create gradients or sharp lines.

Caps / Nozzles
Interchangeable spray-can tips that control line width and spray texture. Common types include skinny caps, fat caps, and specialty caps.

Drips
Intentional or accidental paint drips used stylistically to emphasize movement, texture, or raw expression.

Wildstyle
A complex, interwoven lettering style in graffiti characterized by arrows, connections, and sharp angles. Often difficult for non-writers to read.

Fill-In
The interior color of graffiti lettering, often applied quickly before outlining.

Cultural & Contextual Concepts

Urban Intervention
Any action that alters or interacts with public space in a creative or critical way, including installations, performances, or street modifications.

Public Art
Art installed or performed in public spaces, often supported by institutions. Street art can fall under this category when legally sanctioned.

Ephemeral Art
Art intended to be temporary due to weather, city maintenance, or intentional impermanence.

Site-Specific Work
Art created for a particular location where the environment becomes part of the meaning or composition.

Contemporary Art & Visual Culture Terms

Conceptual Art
Art where the idea or concept behind the work is more important than the final visual product.

Mixed Media

Installation Art

Post-Graffiti / Neo-Graffiti
Contemporary artistic practices that evolve from graffiti but expand into galleries, design, or experimental mediums.

Understanding Legal & Ethical Language

Illegal Graffiti
Unauthorized writing or painting on surfaces without permission. Often penalized legally but also central to graffiti culture.

Permission Wall
A legal wall where artists are allowed to paint, often organized by festivals, community groups, or property owners.

Restoration / Buffing
