A person that is really good at being a goof ball and breaking the tension of situations through comedy and playful antics. But at the same time, has a hard time ever taking things seriously or taking responsibility for things, expecting or assuming others will simply come to help out when needed. This is often how little brothers can behave, hence the term.
Sean is always getting parking tickets, and it's 'never his fault.' I used to feel bad, but now I just laugh at him. His older brother doesnt get it, and his mom just always bails him out. I don't get the guy, but he's a blast to be around. He has total little brother syndrome.

James: Yo Loyd, whatchu' cooking?
Loyd: Some Step Brother Nachos
James: Can I have some?
Loyd: Fuck no, get your own.
