Just to illustrate how slow work is today, I took time to research ...
The Denki Amma. A commonly used wrestling move among Japanese schoolboys, the denki amma gives your opponent an ambiguous blend of pleasure and pain. One boy grabs the legs of the other, lifts his right foot, strategically places it on the other dude’s shaft, and then launches a series of rapid foot taps. Slightly painful, enormously submissive, and awkwardly erotic, the denki amma symbolizes the kind of male bonding that women and foreigners most likely will never fully understand.
More like the kind of bonding I would not like to understand lol
