Webster Dictionary(0.00 / 0 votes)Rate this definition: Freebase(5.00 / 1 vote)Rate this definition: Decadence is a luxurious self-indulgence. It is often used to describe a decline due to an erosion of moral, ethical, or sexual traditions.
The phrase decadent food is meant in a tongue-and-cheek way because the noun decadent actually denotes something that is decaying or in decline.. The term relates to the idea that certain food types are so indulgent that they must be bad for you. Pete Saloutos/iStock/Getty Images.
