French fries served after 9 pm at fast food restaurants. these fries are usualy stale, soggy, chewy, burnt to a crisp, or otherwise sub-par. It is nearly guaranteed that if you order fries late at night from a fast food place, there will be something wrong with them.
I just went to mcdonalds and had to throw the fries out beacuse they were night fries. ow my meal is incomplete.
