Because they are! Only joking:)lol To give you a sensible answer Linus, 'Hash' comes from the French word 'hacher'. The word means 'jumble' or to chop into small pieces. it's full name is hashed...
hash browns are potatos chopped, covered in really what ever you want, and deep fried.
Food, like french fries, big macs, cheeseburgers, hamugers, bbq sandwitches, drinks, brefect foods, and many , many, more!
Not really anything. I've never heard of fancy hash browns but they sound more detailed and have a better taste.
