Throw Up

A throw-up or "throwie" sits between a tag and a bomb in terms of complexity and time investment. It generally consists of a one color outline and one layer of fill-color. Easy-to-paint bubble shapes often form the letters. A throw-up is designed for quick execution, to avoid attracting attention to the writer. Throw-ups are often utilized by writers who wish to achieve a large number of tags while competing with rival artists. Most artists have both a tag and a throw-up that are essentially fixed compared to pieces. It is mostly so because they need to have a recognizable logo for others to identify them and their own individual styles.
