金刚不带罩超人不戴套
[jīn gāng bù dài zhào chāo rén bù dài tào]
Using humor, this translates roughly as 'King Kong doesn’t wear a helmet; Superman doesn’t wear a condom,' implying a reckless attitude or bravado. It combines pop culture references with cheeky commentary on invulnerability or neglect of precautions.
