A horse girl is a girl that is obsessed with the attention she gets from her horse, loving her horse, and maybe even taking a love interest in her horse. The "horse girl" phenomenon was created on the app Tik Tok. She walks on all fours, impersonating a horse, and eats what a horse eats, carrots, apples, etc., and of course, all she talks about is horses! She is also very disliked by her peers, and no one besides other horse girls wants to be around her.
Man, Mollie is such a horse girl! She is SO weird.
