>>16405505In parts of northern England, people might refer to any kind of sandwich as a butty, whether it's in sliced bread or pic rel. Where I live, we would call pic rel a cob (chip cob, egg cob etc.) but sometimes specifically chip cobs are referred to as chip butties. In different parts of the country pic rel might be called a barm, bap, cob, bread cake, roll, and probably many other regional variations.
