pirate ship poo

Kind of stool that you go "arrghhh" when pushing out but when you look in the toilet they are gone, disappeared, vanished in troubled waters...

- Who just destroyed the toilet?
- I did, soz.
- Dude, must've been terrible looking. You should've taken a photo of it and sent it to Guiness records.
- I didn't get a chance, was a pirate ship poo...
