Y.C.S.S. (Younger Cuter Sister/Sibling Syndrome)

When you have a younger sister/sibling that is better looking than you

Stacie is okay but have you seen her little sister Jessica? Stacie totally suffers from Y.C.S.S. (younger cuter sister/sibling syndrome)

Younger sibling

A little pest who likes to burst into your room while your doing homework, or playing on your phone. They like to hit you, then like a little bitch, they tell your parents when you hit back. In other words...they are annoying. They are so annoying they make you feel like banging your head against the wall so hard you lose all your brain cells.

You: *on your phone*

Younger sibling: *bursting into your room and runs up to you* Hey!

You: Go away.

Younger sibling: No! *Slaps*

You: *Slaps back*

Younger sibling: ....MOooOOoOoM *ugly sobs*

You: GODDAMNIT *bangs head against the wall*

Younger sibling

A member of the ape species Annoyus Stupidus, this animal is treated by parents as god, and cannot make any mistakes (even though they do). They possess the evolutionary ability to shift all the blame to the Older Sibling. This means that whatever they do, whether it’s starting an argument, attempted murder, and the like, it’s your fault.

“But moooooooom, he started the fight!” “Shut up you stupid bitch! He’s the younger sibling, you should’ve known better!” “But he...” “I don’t give a shit who started what!”

Slap Your Younger Sibling Day 

On October 4th, anybody who has a younger sibling can slap them, and they cannot fight back, cry, or complain. They must accept the slap.

Older brother: Hey, guess what?
Younger brother: What?
Older brother: It's Slap Your Younger Sibling Day!
Younger brother: Fine, you can slap me.
