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.”

An Australian boy who loves hugs and cares a lot about his fans. Usually is seen with blonde hair but dabbles in dying it dark. The person may also have seagull like arms and dimples. If you see this person roaming the streets, yell "boomer!" and go give them a hug :)
Person A: Hey, did you see that guy with abnormally long arms?
STAY: Oh yeah, don't worry. That's just boomer Chan going to buy some milk.
