1.
A really shitty movie, that you could watch a million times and it would never get boring.

Starring:
Aaron Eckhart as the scientist who tries to save the world
Hilary Swank as the hot chick
and Delroy Lindo as the black dude who sacrifices himself
Me: Hey man, what's on tv tonight?
Friend: The Core.
Me: Aww that sucks, i've seen it like a million times.
Friend: You wanna watch it?
Me: Hell yeah!

A way of life that exudes confidence and fearlessness in social situations.
Phil channeled The Core during his conversation with an attractive woman and sealed the deal.

3.
A Shadowy cabal of highly influential people.

It is rumoured the group meets sporadically at 'The Bunker', but this is unconfirmed.

The purpose of their meetings and the number of members is unknown.

rumoured members go by the code-names
Milesey, Shep and Shoey.

Though there is also a counter-rumour these names were leaked by the group itself to throw off the scent of the many people trying to infiltrate and expose them
I'm just off to a meeting of The Core, LOL Jk, nobody knows who they are or what they do.

snobby group of bitches that think they are the prettiest girls in school, obviously they are extremly confused. They usually travel in packs of seven, and have too great of a love for themselves
-OMG, did you know whitney, ashley, and bobbi are forming the core?
-Seriously, how gay is that!?!

The flap of skin between the balls and asshole, after not showering for a good day and having a thin layer of filth on it. Pimples and hair are common too.
Get in the shower and clean your core!
