The act of rewiping your ass - usually about 30 minutes after taking your initial shit. This act of rewiping has to occur to relieve your ass from the itching that is so freaking bad and you know that either some shit is still clinging to your ass or shit has mysteriously reappeared. Immediate relief is usually felt afterward
Me- I think I have to do a residue wipe.
Wife- What the he'll is that?
Me- Well , I took a major shit earlier and now my ass (It is usually self explanatory after that)
