Older Brother 

a genetic disorder of having a male older sibling. They have two objectives on life, one to annoy the living piss out of you, and two to protect/ teach you.

"My older brother is a total prick."

"My older brother helped me work on my spiral, now i can throw twenty yards farther."

"My older brother beat the shit out of my ex boyfriend, when he tried to rape me"

Older brother 

A really annoying sibling

Examples:
You: Hey can I show you something?
Your older brother: Get out of my room

You: Can you help me with this
Your older brother: Do it yourself

You are trying to fap in the bathroom and your brother knocks on the door and tells you he need to go.
You open the door and your brother washes his hands and walks away
