The orgasmic squeal, often combined with hyperventilation, a little girl makes when one or both of her parents presents her with a pony.
Rich father one: So I gave little Portia her first pony the other day
Rich father two: Did she have a ponygasm?
Rich father one: A ponygasm? What's that??
Rich father two: She gave this orgasmic squeal and started to hyperventilate, it's great. Chloe had a ponygasm when I gave her first pony, too.
