A man who wears a silicone horse mask and dances around with friends who hold a boom box often playing dubstep. Party horses are quite popular at high school cross country meets. The horse and its maens are loved by all.
"Look at those cross country guys with the party horse, those maens are probably having a great time!"

a secret party lead by horses.
usually containing vodka spiked hay and other tight ish like that.

horse parties only allow horses so unless you have some sort of magical transforming into a horse power, you will probably only hear legends of such parties.
they are way more fun than any party hosted by college kids.

like most other parties when the horse owner is coming to check on the horses they neigh "5-0! 5-0!"
"neeeeigh! someone spiked the hay! the horse party is about to craaack bro!"
