swim shorts [noun] [de zwembroek, de zwembroeken]

Example:
“Mannen dragen een zwembroek, maar vrouwen dragen een badpak of bikini.”
(“Men wear swim shorts, but women wear a bathing suit or bikini.”)

Instead of “badpak”, one can also say: “zwempak”.

Dutch slang: “ballenknijper”.
This word literally translates to “balls pincher” and is used to
describe the tight male swim wear that looks like underwear (“speedos”),
that middle aged Dutch men tend to wear.
