Keep your nose clean
Meaning
To stay out of trouble and avoid engaging in any illegal or unethical activities.
Origin
The phrase 'keep your nose clean' likely emerged from the gritty realities of early 20th-century urban life, where maintaining physical cleanliness often mirrored one's social standing and adherence to legitimate paths. A dirty, bloody, or drug-stained nose was a visible marker of involvement in fights, illicit activities, or substance abuse—all leading to trouble. The literal act of keeping one's nose free from such tell-tale signs became a sharp metaphor for staying entirely clear of criminal enterprises or any behavior that would invite legal repercussions, evolving into a stern warning to avoid trouble and uphold one's reputation.
Examples
- After his last run-in with the law, John promised his mother he would keep his nose clean from now on.
- The detective advised the new informant to keep his nose clean if he wanted to maintain his plea deal.
