Similar to "dummy text", "text filler" or "greeking". Gack is anything used in a design as a temporary place holder before being replaced by an actual design element. For instance, filling columns of text with "Lorem ipsum dolor...", or using a textured box where an image or other design element might go in a layout.
Gack can also mean something in an image or design which serves a technical purpose that is intended to be removed in the final product, such as tracking dots on a plain wall being filmed, or a wire harness on an actor that needs to be painted out.
