Grogan 

"A spa for the balls"
A grogen consists of a male or female gargling a various liquid and then their partners testicles are dipped into the liquid. This will create a spa like environment for the testicles to rest in.
A painful grogen is when the giver of the grogen chokes on the liquid and closes their mouth quickly, potentially harming the receiver.

The most coveted grogen are given by elderly individuals. Also known as the "senior grogen", these grogens are world renowned throughout nursing homes.
