Throw up (graffiti)
Throw ups, or throwies, are a form of graffiti that fall between tags and pieces in complexity. The name comes from the way they are designed to be "thrown" onto a surface as quickly as possible. They are almost always done with aerosol paint.
Form
Throw ups are typically the writer's moniker in large "bubble-letters", with or without a fill. Throw ups without fills are called hollows. Throw ups are sometimes done using only the first two or three letters of the moniker in a throw up to quicken the process, especially if the writer uses a longer name. Throw ups are done with fast, pre-planned body movements to enhance speed. This speed means that writers can produce large amounts of throw ups in a short time, especially when compared with pieces.Defining characteristics of skilled throw up include letter height consistency, letter shape conformity along the top and the bottom, minimal negative space, and clean lines. The line between pieces and throw ups is sometimes blurred, but throw ups tend to be faster to paint, have fewer colours, and prioritise speed over style.
