When somebody takes a nasty
shit and does not wipe properly causing some fecal matter to decorate their
underwear. They leave a trail
mix of poop in their underwear.
Billy: Dude I just
shit and I feel
like there is some residue in my boxers.
Harry: you must wipe
better so you dont have trail mix in your boxers.
Billy: Thanks for the tip. I will wipe better so I do not have trail mix in my boxers next time after I poop.
