Ok Boomer is a term used to define people who were born in between the years 1944-1964, which is the year of the baby boom, hence the term “boomer”. Ok Boomer is when one of them says something like “Back in my day...” or “We used to...” and a person just says it for fun or if they’re mad. Most commonly used in school in front of old teachers.
Teacher 1: Back in my day, when I was 16, these were the most popular songs! *Plays a song from 1960*.
