5. OK -- I had to google it

A chip butty is a sandwich made with chips (i.e., French fried potatoes) on buttered white bread or a bread roll, often with an added condiment such as ketchup, brown sauce, mayonnaise, or malt vinegar.

The chip butty can be found in fish and chip shops and other casual dining establishments in the United Kingdom.
It is also less commonly known as a chip sandwich, chip batch, chip roll, chip muffin, piece and chips, chip piece, or chip sarnie.

One variation is the chip bap or chip barm, which uses a floury bap or barm cake instead of sliced white bread.
In the East Midlands a chip butty made with a bread roll is referred to as a chip cob.

A chip butty can be vegetarian if the chips are not fried in lard or dripping.
