This is the act of putting the tip of your penis into a condom and filling it with urine and then jacking off (or preferably having a girl...or guy if that's your preference, do it for you) into it. Voila! millions of little white fishies swimming around in a tank full of golden liquid.
Dude, I went over to cindy's house the other night and we made an erotic aquarium.
