Derogatory word for any female considered worthy of screwing. From “grommet”, meaning a rubber insert (with a hole through it), placed in a hole through metal or some other hard or sharp material, to protect a wire or pipe that passes through the material. This intimates a safe and comfortable hole into which you place your dick, cock, schlong, etc. etc. etc.
