Kittie: Apple core,
Mellow: Tell me more.
Kittie: Who's your friend?
Cath'goe Ren: If I get hit with an Apple, I'm going to make sure you both are eating threw straws for a year.
The apple core bit stems from an American kid's joke/prank/game sort of thing. It doesn't really mean anything. but tends to end up with some one getting hit with an apple core. Fairly nonsensical, it start's when a kid finishes an apple,
