This was a technique used by the German/Nazi army in WWI. In order to create a larger, stronger army for a future World War that the Germans had already known would happen, they would line many healthy and strong men in a line and order them to masterbate in an orderly fashion. Each man would have a partner placed across from him with a bucket in between the two of them. The two would take turns, and be forced to provide seman 16 times per pair. If the pair does not meet the requirement, they were severely punished. Most of these lines would take place in small warehouses with roughly 480 men, 240 pairs. After the collection of seman, the officers would ship it to fertilization facilities where a similar practice would happen with women but instead of producing, they are using the produced seman from their male peers.
This practice is often used today at college parties.
Jizz lines were an awful, inhumane, and oddly kinky practice used by the Germans many decades ago.
