Code Infection
Noun · Slang & Abbreviations
Definitions
The spread of a bug, anti-pattern, or bad assumption from one part of a system into many others. In engineering slang, code infection captures the way problems propagate by copying, dependency, or shared utilities.
In plain English: The spread of a bad bug or pattern through multiple parts of a codebase.
Example: "One unsafe helper function caused code infection across the stack because teams copied it into services and scripts without revisiting the original risk."
