jizz rag
Something used to wipe up semen after masturbation, or alternatively, masturbate into if the pervert in question is somewhere where he'd perfer to leave things as they were when he entered - such as a friend's house or that of his parents. Can be anything from age-old classic, the dirty sock, to a hand towel.
When selecting some random scrap of fabric for use as your jizz rag, do remember that semen can leave unsightly stains on black fabrics.
