Some annoying ass old person who thinks they’re the only person alive/thinks they should have it their way because they’re old.
Old person: “It’s not nice to stare at your elders.”
Then stares at a young adult because they have piercings or/and colored hair
Young adult/Teen: “Okay boomer.”

Boomeritis is an illness that forces the infected to talk like old British men from the 1800’s. It can be fatal in some situations, but the worst cases tend to only cause lasting damage to the brain and how it functions.
