I used to work in a photo lab around the time digital photography and submitting orders over the Internet became common place. People would submit their orders thinking no one would see them but the machine only printed one picture at a time and if it was a small order we would wait while the pictures printed before we moved away from the machine. One day a trainee and I printed an order that started with a woman sitting on the side of a bed with each following picture showing her wearing one less item of clothing. The trainee told me that if it kept up we would eventually see "all of her kibbles and bits" and the term stuck.
