A girl who wears t-shirts with horses on them and tapered denim pants, has really long hair in which they braid and fasten with a scrunchie in the back of their head, will "gallop" on the track during gym class, is only friends with other girls who like horses and will look down on you because you are not a horse.
The woman I worked for used to be a horse girl, she had an entire wall full of just pictures of her with her horse and always talked about the weekends she would spend riding them.

A horse a girl is a crazy girl who has an obsession with horses, she doesn’t not admit that she is but she does call herself an equestrian, they usually talk about them all the time and act as if they actually are one, some horse girls even gallop and eat hair and grass (careful she might bite you if you’re not looking) . Usual names include; Emily, Maddison, Jemma, Sarah, Jessie, Emma
Non-horse girl; “Omg it’s a horse girl!”

Horse girl; “I’m not a horse girl, I’m an equestrian

Non-horse girl; “uhhh ok then

A crazy, middle class, white girl who is obsessed with horses. In general this specie of human is exceptionally horny and extremely kinky. So if your girlfriend's a horse girl, watch out because she's definitely gonna take the reins in the relationship.

A kinda crazy, unforgettable girl. Sometimes they go through a lot, but they always have their horses <3 sometimes introverted, sometimes not. Just take a chance and get to know them! They will come to school with stories of falling off horses, what horse they rode, and no one else will care- except for their fellow horse girls. They "jump" "gallop" play with toy horses (even when they're older!) They HATE people who insult their horses.

Like a horse woman, except younger and less experienced.
Who's that weirdo?
She's a horse girl.
Get to know her! She's nice. Sometimes.
