a chip butty is what you make at home with your bread and butter ( all meals come with bread and butter, i love bread and butter) folded around the last few chips, usually with gravy wipings. a chip barm is what you get from the chippy, a big, flattish, floury, oven bottom muffin. they cost about 55p, or 85p if you get it in a cone, a cone of paper with the barmcake in, sliced and buttered, with a huge portion of chips piled on top, more than can possibly fit in the barm so you have to eat the hot chips with your fingers until you can fit the rest in the barm which is now all chip-greasy chip-tangy on the inside and crisp on the outside. or there's your chip naan, which is basically a naan bread, with cheddar and coriander (usually, you can have garlic or plain) baked in and then the chips are rolled up in the naan. or you bake the chips inside the actual naan, but there's only a few places that can do that properly, otherwise you end up with a sort of spicy chip pizza, which is minging. it's a classic whichever way you slice it.

god i love chips
