This act is when you stand behind someone who is sitting while cupping your testicles. As you move along side this sitting person you say "
Eric" and drop your testicles and say "Verdonk" as they make contact with the shoulder of the sitting person.
This was a well known party trick of the late New Zealand Olympian
Eric Verdonk, and is classed as a formal greeting in New Zealand, often referred to as the "white
man'
