Second sibling syndrome 

1. Always craving the attention the first born sibling recieves from parents; wanting the recognition from parents; Always striving to "one-up" other sibling, to hopefully recieve attention from parents.

2. Usually has some degree of rebel in them; mostly in the wrong when in altercation with first sibling.

3. Willing to fight to the death over petty things to show parents that first sibling is in the wrong.

4. The cure for this syndrome is when the First sibling leaves the household, therefor leaving parents to become attached to Second sibling, until First sibling returns to home for a short stay(s).

Joe: "Mom, I swear to moses Mark punched me !"

Mom: "Of course hunny, I can not believe I am even questioning your integrity."
