Used as a joke or act of revenge. Smudgin is the act of wiping your dirty, bare ass on an object such as the armrest of your roomie's favorite chair, someone's car door handle, a toothbrush. Pretty much any object that would not normally have object to rectum contact. Smudgin is akin to the Texas Doily
