Boomer
/ˈbuːmər/noun
A person belonging to the baby-boom generation, or, more broadly, an older person stereotyped as out of touch.
Did you know?The slang sense comes from the post–World War II baby boom, while the older root *boom* entered English as a loud, sudden noise—an onomatopoeic word that literally sounds like impact.
