When an uncircumcised male pinches the top of his foreskin and then begins urinating, the inside of his penis fills up the same way a water balloon would if you filled it with water. Thus creating a penial water balloon. It is fun for the man to then aim and let go to try and get all the urine to splash right into the toilet bowl, although he will pretty much always miss completely and splash his urine everywhere else.
Making a penial water balloon is a good way to clean out all dirt and gunk that constantly gets trapped under my foreskin.
