When a group of people talking group up into a circular form. The way washing machine functions is that a person is pushed in the middle of the circle and he is 'ganged up on' being continuously pushed around the circle.
If someone you dislike is in front of you in a circular conversation, push him in the circle, so everyone will gang up on him and push him. Use the word 'Washing machine' to alert everyone to gang up
