Laziness (also called indolence) is a disinclination to activity or exertion despite having the ability to do so. It is often used as a pejorative; related terms for a person seen to be lazy include couch potato, slacker, and bludger. Feelings of laziness may be a symptom of mental illness, or a medical condition. Chronic laziness may be an underlying psychological condition.

One of the seven deadly sins in Catholic thought is sloth, which is often defined as spiritual and/or physical apathy or laziness. Sloth is recommended against in the Epistle to the Hebrews, and associated with wickedness in one of the parables of Jesus in the Gospel of Matthew. In the Wisdom books of Proverbs and Ecclesiastes, it is stated that laziness can lead to poverty. According to Peter Binsfeld’s Binsfeld’s Classification of Demons, demon Belphegor is thought to be its chief demon.
