Used by people experiencing irritable rectal itch (skin irritation in the anus & surrounding area), a wipe scratch is used as a method of relieving the itch. The subject simply takes a handful of wadded (or neatly folded depending on perference) toilet paper and violently wipes the irritated area. The motion is usually done front to back although back to front is certainly acceptable as a means of equal relief. Often times the method of scratching is said to create blood, which may be caused by already existing gashes in the anus, which could be from hard stools. The method is becoming increasingly popular as a means of anus scratching as scratching with bare fingers is both unsanitary as well as dangereous.
