speedo

A proper and very common swimming costume favoured by people young and old worldwide, except in the United States. The speedo-style suit is form-fitting, which allows for better control in the water, faster drying, and more comfort. Since Europeans, Asians and Brazillians don't obsess over penis size or automatically associate speedos with homosexuality the way Americans do, people of all shapes and sizes can wear them while swimming without ridicule.
