older sister 

A living heck. She is always the most mature and never understands what the younger is going through. She can be good to have around and can have your back sometimes.

Mom: Younger, the older child is getting a new phone and you're not allowed to have one until you're her age.
older sister: yes as it should be.

older sister theory 

the theory that states that all older sisters are hot no matter what

if some girl is ugly and then has a younger brother born
she will miraculously become hot

the older the younger sibling, and the better you know them, the more satisfactory it is to gawk at their sister
especially if the younger sibling is male

if there is a not hot older sister:
1-they have a penis
2-they have a disorder
3-they are bangable at the very least
4-they do not really have younger siblings
5-you are living a lie

guy1-i bet your sister is hot
guy2-how would you know?
guy3-older sister theory, duh.
guy1-id love to watch her in a porno
guy3-rule 34 man
guy2-i assure you there is no porn of my sister
guy1-rule 35
guy2-blasts
