Noun:
A box used in porch fishing that is placed on a porch or stoop as bait for mail thieves, aka "Porch Pirates" to be intentionally stolen. They sometimes include animal feces, or gross things to add some payback and hopefully deter the thief from stealing in the future.
Some on YouTube have gone more elaborate and built glitter flinging devices and boxes attached to shot shell primers to scare the thief.
"I buy my bait boxes at porchfishing.org. They have the freshest shit around."
"If you need a decent bait box go to porchfishing.org for all your dog shit needs."
