2.
The sudden and dramatic freezing of the male ejaculate when the ejaculation occurs in or into a profoundly cold environment, such as a polar vortex, a meat locker or a frost giant's vagina.
Last night, out side of the bar in Rochester, I had a massive cryojaculation when Cindy gave me a hummer in the alley. That'll teach her to dish out back alley hummers in January during the Polar Vortex!
