Code Quicksand
Noun · Slang & Abbreviations
Definitions
A part of the codebase where every attempt to fix or improve things seems to drag you deeper into more hidden issues. In engineering slang, code quicksand is dangerous because escape gets harder the more effort you apply without a better plan.
In plain English: A part of the code that traps you in deeper complexity the more you work on it.
Example: "The serializer was code quicksand, pulling every cleanup effort into old compatibility paths and undocumented edge-case handling."
