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.

Younger sibling

When you get a younger sibling, you have a 90% chance of the devil swapping it out with one of its minions. The other 10% of babies passed the devil's vibe check and was able to stay. These few specimens are the rare case of a well-behaved kid. If you have one, consider yourself lucky.

Kate: I have a younger sibling now!
Amy: so do I!
Kate: wtf you are my younger sibling
Amy: *sweats nervously*

Kate: The hell?! Mom! The baby's sweating, and its flooding the kitchen!

Younger Sibling Privilege

A phenomenon in which parents allow their younger children to participate in certain activities that they did not allow their older children to participate in when they were that age.

This is an example of Younger Sibling Privilege: When Johnny turned 16, his parents told him he could not work toward earning a drivers license. When his younger brother, Timmy turned 16, his parents registered him for driving school.
