The GEN-Z word “boomer” generally means an old person, or a gen-x. It can be used in a disrespectful manner calling some one old, so be careful not to say it to a “Karen”
Short for baby boomer which was the name of babies born between 1946 and 1964, so it is the correct terminology that the government uses. Therefore is not a insult
