a person who is wiping one's self with a generic brand or a one-ply piece of toilet paper after defacating will often experience a brown finger surprise. a brown finger surprise is caused by ungraceful shoving of toilet paper into one's butt hole with such force that it will tear at the pressure points (fingers) thus causing left over excretments to lodge into one's fingernails or get stuck onto other parts of their finger. to avoid a brown finger surprise be sure to by two-ply or double or triple fold the one-ply sheets.
