Filly Cheesesteak 

A hot sandwich combining process cheese and sliced meat of questionable origin.

I can vouch for the cafeteria's Filly Cheesesteak: she was definitely less than two years old.

I'm a 16 year old brony, and I grew up with MLP:FiM and I was a Filly Brony during when I was 4-8 years old.

A purposeless interpretive dance involving finger-to-cheek pokes done by girls. This dance is aimed to further prove the dancers' inane and insignificant existence. It is uselessness at its worst.

Girl 1: Uhh, uhh break it down! Silly it, filly it!
Girl 2: Silly filly!!!!!
Girl 1: Bob! Do the silly filly!
Bob: (walks away)

Bucking Filly 

The art of fucking a girl from behind (vaginally) and then pulling out and forcefully sticking it in her ass thus causing her to kick backwards in a bucking fashion. The bucking will normally be in the old nutsack area which may be pleasureable to some men.

I've always wanted to date an equestrian, but I am afraid she may be a bucking filly.
