willypoo

The word 'Willypoo' is often described as when detritus (poo) falls out of your Penis (willy). This gives the man a lot of pain but much joy after he has finished

Commenly used by those who arn't born with a penis but instead get a fake one.
They then have problems such as when they try to shit, it comes out of there penis instead of they're anus. This has been proved by over 1 million scientests such as einstein and lots more.
