five by five起源于20世纪40年代的军事无线电通讯系统，原指信号强度（Strength）和清晰度（Clarity）均达到最高等级（5/5）。这一术语在1950年代通过美国海军陆战队和航空领域的广泛使用，逐渐从专业术语演变为日常俚语，引申为"一切正常、一切顺利"或"状态极佳，非常成功"。其语法功能灵活，可作表语（如"Everything is five by five"）、状语（如"Running five by five"）或独立应答（如"Five by five, loud and clear"）。紧急情况下可替换为"green light"（通行许可）或"all clear"（解除警报），但"five by five"更强调持续稳定状态。
