To Dyson is the name given to the act of sucking up ones recently ejaculated semen through the eye of the penis. Most commonly caused by the victim being interrupted during masturbation during climax. This shock leads to the testicles expanding slightly internally, thus creating a vacuum inside the testes which therefore sucks the semen back into the testes. If done on a regular basis this can cause severe aching of the testes and may cause one or both of them to pop violently and randomly, normally when sexually aroused.
