Denkianma

Denkianma is a popular Japanese prank played between two people where one person puts their foot into the genital area of the other and shakes it in a vibrating motion. Often this is done by grabbing the other persons two feet to complete the action. This is often done between school aged boys as a prank similar to Kancho and could be seen by a western audience as a type of bullying. Recently the crisps company Doritos released a new flavour of potato chip called "Denkianma"

The history of the name comes from the combination of two words. Denki "電気" meaning "electric" and Anma meaning masseuse. This is because to the victim the vibrations caused by the prank feel similar to an electric massage machine.
