Great picture to illustrate the point. I know exactly what you mean:
Last weekend, I was on South Beach in Miami. The weather was warm enough to be on the sand on the beach yet a little too chilly to spend any significant amount of time in the water. When I arrived at the beach, I positioned my beach blanket behind an Italian man who was wearing a navy blue speedo with blue lightening streaks. He had just left the water and was drying off with his towel. He didn't have much of a frontal bulge, but when he bent over to dry his legs, his bulge hung like a hanging basket of melons between his legs.
