surrogate older sibling

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.

Grand siblings

When you have siblings with an 18+ year difference.

John: “My dad called me the other day and told me I’m about to have twin sisters. He’s 60 and I’m damn near 35!”
Jim: “You got grand siblings that’s crazy.”

when someone dates one sibling, they break up, then the person dates their brother, then on and on with the family like how a homie hopper jumps homies, but it's siblings

Sibling

Someone who invaded your life through your mother's uterus (Or an orphanage)
They drive you mad and you drive them mad, but no one else can drive you or them mad.
They ruin your life but they kinda don't
Siblings are confusing little shits
And they are also little fucking snitches

Sibling: "HEY I NEED--"
me: "SHUT DA FUC UP"
Sibling: "But someone is bullying me!"
Me: *I'll kill them*
