Frieddough is a North American food associated with outdoor food stands in carnivals, amusement parks, fairs, rodeos, and seaside resorts (though it can be made at home).
Frieddough is the specific name for a particular variety of fried bread made of a yeastdough; see the accompanying images for an example of use on carnival-booth signage.
Native American Indian fry bread is another similar deep-fried bread and may have inspired frieddough.
