Tech Debt Snowball
ELI5 — The Vibe Check
A tech-debt snowball is when you avoid paying down small tech debt, it compounds, and six months later the simple feature you want to add requires rewriting three subsystems. The snowball has become an avalanche.
Real Talk
A tech debt snowball is the compounding cost of deferred maintenance: each new feature built on top of unaddressed debt adds more debt, multiplying the eventual cost of fixing the underlying issue. Unlike linear technical debt, snowball dynamics mean delay is quadratic or exponential. Preventive maintenance and refactor budgets keep the snowball from forming.
When You'll Hear This
"That config module is a tech debt snowball — touching it takes a week." / "Budget 20% of each sprint for snowball prevention."

Entropy Tax
Entropy tax is the cost you pay every time you touch a messy codebase. Every new feature takes 20% longer because the code is tangled.
Legacy Tax
Legacy tax is what you pay for maintaining old systems that nobody wants to touch.
Refactor
Refactoring is cleaning and reorganizing your code without changing what it does — like tidying your room without throwing anything away.
Technical Debt
Technical debt is the coding equivalent of putting things on a credit card.
