Commando

Going commando means choosing not to wear underwear beneath your clothing. The phrase entered wide slang use in the late 20th century, and its exact origin is uncertain, though it is often loosely linked to military lore about soldiers skipping underwear in the field. In gay male culture and beyond, the term is used casually and often playfully, sometimes carrying a hint of confidence, comfort, or sexual readiness. It is not tied to any identity or orientation and is common across many communities. For most people it is simply a personal choice about comfort, practicality under certain clothes, or a private sense of freedom.
