A form of torture whereby a large male dog is aroused to the point of having his penis come out. The victim is then strapped down and the dog ordered to sit on the victim's face. The "sandwich" is formed by the victim's lips, which act as the "bread," and the dog's penis, which becomes the "meat."
The Al Qaeda terriost told us everything after we administered 75 straight hours of Pink Sandwiches. He was psychologically bruised, yet was physically unharmed (with the exception of badly needing a breath mint.)
