Older siblings as bullies towards their younger siblings as well as others. However, if the victim in question is an Annoying Younger Sibling towards them, the work may use this as an attempt to justify it. In some works, maybe the older sibling was compared by their parents, or their parents care more about the younger siblings.
Related tropes: Kids Are Cruel, Teens Are Monsters (because the big sibling is often a teenager as compared to the younger more sympathetic protagonist). If one child is abusive to their parent, rather than sibling, it's Abusive Offspring. A Big Brother Bully who has been Promoted to Parent might, functionally, become an Abusive Parent.
Compare Aloof Big Brother, Sibling Rivalry, Cain and Abel. Contrast Big Brother Instinct; oftens mixes with it in the "The only one allowed to hurt my little brother is me!" sense.
Do not confuse it with Big Brother Is Watching, even though a totalitarian state, like a bully, can use physical force to intimidate its citizens into submission.
Unfortunately, very Truth in Television... and even a big sister isn't exempt.
