Code Flu
Noun · Slang & Abbreviations
Definitions
A joking term for a codebase that feels generally sick, sluggish, and full of minor problems everywhere. In engineering humor, code flu suggests the system is not catastrophically dead, just unwell enough to drag down everything around it.
In plain English: A joking way to say a codebase feels generally unhealthy and buggy.
Example: "After the dependency refresh, the admin app had code flu, with flaky tests, random warnings, and small regressions appearing in every corner."
