Playground ruction procedure (UK c.1970's). Combatants remove their arms from sleeves and stuff them inside the trunk of their gansies, leaving just a set of waggling digits for attack. As per flid fight but with addition of the kneeling into shoes in order to complete a quadripegically stunted effect. Serious injury rarely ensued but a tried and tested upsetter of harassed dinner ladies, babysitters and nana.
"Having an older brother meant I invariably came off worse in sibling ructions but I always gave His Royal Highness proper competition when we matched up for our annual spina fight,"
