A pie in which you stick a plastic horse or pony figurine to celebrate a friend's birthday. Especially used if the figurine is Pinky Pie or is wearing a party hat.
We were too broke for candles this year and the store was out of cakes so we got him a party pony pie instead to celebrate in style!

A gathering of only women. Opposite of "sausage fest." The only difference is that women don't care that there are no men present.
"This is a really great pie party. We should get together more often. Sometimes I just need a break from men."
