Rubber ducks that JEEP cult members keep in their rectums until they see another JEEP in a parking lot, at which time they remove the rubber duck from their rectum and place it somewhere on the newfound JEEP as a gift. If the JEEP belongs to a fellow cult member, they will display their ass-scented gift on their dashboard until the scent wears off at which time they put the duck into their rectum and repeat the process.
Someone ducked my Jeep! I hope I don't catch C. Diff from this JeepDuck
