spoil
This word carries a strong sense of degradation, whether it is the physical decay of organic matter or the moral decay of a person's character. When applied to people, it suggests an excess of indulgence that leads to entitlement or behavioral issues, shifting the meaning from destruction to over-satisfaction. In a modern digital context, the term has evolved into a specific social taboo regarding the premature revelation of plot points. As a noun, the word refers specifically to displaced earth in engineering or mining, a technical usage that is entirely distinct from its common verbal senses.
