gack

Methamphetamine (crank, speed). Describes the gag reflex triggered by the extreme burning sensation of the nasal passages when the drug is snorted, and the very bitter taste as it drains down the back of the throat.

The character 'Pooh-Bear' in the movie "The Salton Sea" had to have his nose surgically removed because he snorted too much gack.

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.

"We need the actual text so we can replace the gack in the layout before sending it to print."

"The VFX Artist will have to paint out all this gack that is in the shot before it can be used".
