the act of slashing one's own hand (i.e., with a hunting knife. broken beer bottle, or any other appropriate device), then using that hand to jerk off (if you're a guy). Particularly good for cutters, this way you're killing two birds with one stone. For girls, see redrum stabby.
Bob really knows how to relax at the end of a long day with a good redrum slappy.
