Little Brother 

The younger, dumber, incompetent version of Big Brother. (referenced in George Orwell's 1984) Claims to have control over society, but is really a bumbling idiot.

Little Brother was responsible for allowing a man to fly cross-country with an expired boarding pass and nobody stopped him at one of the many checkpoints along the way.

Little Brother 

Once your parents realized they were gonna be stuck with you for 18 years they tried for another.

That's your younger brother, he is always annoying you and seems to take pleasure in blaming you for things and making up fights altogether.

Once in a while, you might have actual fun with him but most of the time he just walks into your room without knocking.

Person 1: Bro I think my little brother is jerking off on the toilet.
Person 2: What? How do you know?
Person 1: There is always jizz fucking running down the toilet seat, he's a fucking idiot.
