jizzcano
An eruption of semen so virulent in nature, that its properties upon ejaculation or more akin to a volcanic eruiption than protein secretion. Causes agonizing pain, followed by extreme sense of relief, and is often accompanied by testicular pain very similar to blue balls.
I had not had sex in 6 months, so when I ejaculated in her mouth, she ended up choking on my jizzcano.
