A really nasty or wet fart that leads you to believe you may have sharted, or used for comic effect.
*BRRRRRRrip* Oh yeah, that's a wiper!

Unit of measure of mess in an infant's diaper, described by the number of diaper wipes needed to clean the baby's bottom, e.g. one-wiper, two-wiper, three-wiper, etc. Typically used by new parents. (With experience, parents become more efficient at cleaning bottoms and use fewer wipes.)

The rare (and I mean really rare) instance of bowel evacuation so clean, there is no need to wipe. See also the "No Wiper Challenge", in which you trust your instincts so much, you don't even take a test wipe.
