When Cousin and I were little, we renamed the standard male and female parts with more, um, personally-suitable nouns.
In a move that would turn out to be particularly ironic in my case, the male parts were named "Toy-Toy".
The Toy-Toy is some new equipment in our household and has taken, now, three weeks and 4 days for us to become somewhat accustomed.
Because I am a bit of a data head, I have keept track of such things as, for example, the fact that we have had six "open air leaks." This means, that while changing the young sir, he has peed all over us and everything around us at the time.
