lampoose
The act of tucking a male's junk (aka twig 'n berries) down, up, and under with the ultimate goal of completely hiding said junk from any discernible bulge in the frontal region of his swimsuit area.
Deeeeeeeaaaaaaam! Look at that guy over there by the lazy river pool! You literally can't see any wein-bulge at all. He must have lampoosed.
