Annoying Little Brother Syndrome (A.L.B.S)

Always at least a second child.
Usually tattles
Constantly steals the spotlight
Gets blamed by all older siblings

You know I'd like to go to the club, but my super Annoying Little Brother has some kind of Syndrome or something. I can't get over how whinny he is, and he's such a little snitch, he'll just tell my mom or dad. Stupid Annoying Little Brother Syndrome (A.L.B.S)

Little Brother Syndrome

When a person/organization/whatever noun (#1) feels a rivalry with another person/org/noun (#2), and does everything they can to feel like they are beating the other group, meanwhile person (#2) does not recognize the rivalry at all or does not consider person (#!) a threat.
Named this way because little brothers have a knack for being annoying puntable things

Greg totally has Little Brother Syndrome, when he heard Alysa read 25 pages he read 30 just to be better than her. Little does he know "Learn ABC's with Caillou" is not on par with "War and Peace."

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.
