Short for controlled detonation which occurs when you are having intercourse and are not using protection. Just prior to climax you pull out and transfer the shaft to a secured location in the females mouth. Once the lips have formed a complete seal you release the ejaculation without fear of pregnancy or a sticky mess with stubborn stains. This provides protection to the cervix, eyes, nostrils and external auditory meatuses...or meati whatever. Loss of control can occur with premature evacuation.
