The term 'Bygone Nair Rival' can be summarized by the four-letter word 'NEET'. This acronym stands for 'Not in Education, Employment, or Training', and is used to describe a person who is not actively engaged in any of these activities. NEETs are typically young people who are not in school, employed, or participating in any form of training or apprenticeship. This term has become increasingly popular in recent years as more and more young people find themselves in this situation.
