To squirt so long and hard that your equilibrium is disturbed. Side effects include severe dehydration, massive fluid loss, and/or unconsciousness.
This one chick I nailed with squirtigo, straight ruined the paint on my ceiling from the enormous water pressure flow from her gushing vagina. What a rush...literally.
When a guy who just loves to rub against silk curtains ejaculates so much onto them that they become hard and crusty with dried semen. Ideally they will steadily grow in size until there is at least an inch thick layer of semen caked onto the curtains. At this point they are ready for harvesting. Cut the layer into one inch by one inch squares and sell them to your friends.
"Dried semensquares, directly from my living room squirtains. The melt-in-your mouth feeling that we all know and love!"
