that's where certain key words are pronounced pseudo back wards so that you can communicate but the customers do not know what you are on about. For example the govner would often say "use the old ones first", obviously stock rotation is important but at the same time customers would not like the idea of not having the freshest, so he would actually say "Use the dlo ones", dlo pronounced deelow. Als you's have a "Gel of Beemal", leg of lamb etc etc
