A person who fulfills the vacancy to be the surrogate older sibling in a family where the oldest child has left home whilst the younger sibling(s) are still too young to move out. Such vacancies are commonly found on the Happy Family sticker in the rear windshield of the family car. This role often involves providing guidance, support, and companionship in the absence of the biological older sibling.
After my older brother left home for college, someone became the surrogate older sibling, helping me navigate school and life at home.

Her: Oh, and you know I love you like a brother.
Friend: Ouch, sibling smashed. That's gotta hurt.
