If you asked for a piece of bacon in scotland you would probably get a bacon sandwich (any scots feel free to correct me).

One thing I have noticed has a different name all over the UK is a bread roll. Back in Geordieland we always called it a (bread)bun (only for wimps - everyone else used stottie cake for their butties), in other parts of the north I have heard it called a barm(cake). What does everyone else call it?
