a rough draft or preliminary layout of a proposed design initially presented to the client to show the placement of text, images, and other design elements
use it in real life: Designers show comps to clients so they can see various design ideas and a rough estimate of how the layouts will look when finalized. Some comps can be very ” loose” or “rough” or they can be “tight” or “polished” depending on the level of work required to successfully express a visual idea.
