A stylish young woman.

In Australia, it specifically refers to a young woman dressed up for the Spring Racing Carnival in Melbourne. Additionally, it is usually only used in the plural form.

It is taken from the term for a young female horse before she is old enough for racing.
1. "What a fine filly!"
2. "Check out those fillies in The Birdcage!"

A ship between Finn Wolfhard and Millie Bobby Brown. This ship is 1000% NOT REAL and fans need to chill. Because fans insist on fillie and whenever Millie and Finn hang out they get never-ending messages asking if they are dating Finn and Millie do not hang out anymore.
"Ship the characters not the people" - Millie Bobby Brown
Mileven is totally really though.
Person A: Hey do you ship Fillie?
Person B: NO FILLIE IS NOT REAL
A: Yeah I know right fans need to stop insisting on it
B: Hell yeah they do.

n. fil-ee
noun, plural: -lies

Typically refers to 13-30 year old female fans of the 2010 reboot of the show My Little Pony: Friendship is Magic. Similar as, but not to be confused with: "brony" (bro+pony) which is more often used for the male equivalent. It is a well-known and undisputed fact that bronies are on average about...20% more awesome due to their rarity.
ex. "You wouldn't think she would still watch that show at her age, but she's obsessed. She's a total filly!"
