What I understand is that, man who is showing, intended an excuse to have the zip down, and says that his balls are tight inside of those pants and he is rearranging them
(men with camera): show it! show it! (men who shows): you`re silly. do not show it to the guys. (then he shows, and the guy with camera call for someone named Andre. After this, the guy who showed put his dick inside his pants and the rest is a portuguese too regionalized for me to understand)
