When a man, whose penis is locked in a chastity cage, places a dildo at the place where usually his hard penis would be, and strokes the dildo, tricking the brain into thinking that he's stroking his penis, thus triggering an ejaculation. Similar to how a crippled person would scratch a lost limb.

"Very frustrating, but I've almost mastered the phantom jerk."
In the Nordic highlands, it was widely though to be rude when prince's of lords would pick their teeth with their fingers in a jerking motion, while speaking ill of their house.
This custom was adopted by the Europeans in the 1600's
