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