Ottawa Valley slang. When one sticks a frozen hot dog into one's vaginal recesses. It is kind of like a dildo, or a diller. However, it is smaller, and more dangerous due to the fact that a piece could easily fall off and subsequently become cunt junk. Therefore, it should only be used by professionals.
