A traditional style of wanking originating from Belgium. This is practiced in the shower and can be tricky! you must have one foot in the bath and the other raised on the side of bath. You give it the berries by putting your arm round the back of the raised leg and jack yourself off in a backwards hand (knuckles facing up!), hence the name Belgium Back hander.
