when an uncircumsized male pulls the foreskin of his dick over his knob and starts to pee. the foreskin then inflates to a decent size (about a handful)thus resembling a waterballoon. although rare, this is single handedly the most disgusting and humerous thing ever created
"gebraldo decided to scare his girlfriend into thinking he had a terminal tumor located on the knob of his cock. So he whipped it out and waterballooned that shit"
