The term Lemon-Law is a nick name derived from other common terms
such as Lemon-Car, Monday-cars and Friday-Cars.
A lemon car is a defective car that, when purchased new or used, is found by the purchaser to have numerous or severe defects not readily apparent before the purchase. Any vehicle with these issues can be termed a “lemon car” and by extension, any product which has major flaws that render it unfit for its purpose can be described as a “lemon product”.
