I use the term to describe the introduction of unnecessary abstractions in the name of hypothetical future use cases. For example, using an enumerated collection of values where a boolean would suffice. It could also refer to building resilience to load before it is necessary. Example, distributed databases with failover and recovery capabilities for a side project. Poke holes all you want, those are bad examples, but they should illustrate the point. Over engineering is a real phenomenon.
