Phantom Bug

Definitions

1. A bug that appears and disappears unpredictably, making it hard to capture, reproduce, or explain. In engineering slang, phantom bugs haunt teams because evidence vanishes as soon as someone starts looking closely.

   In plain English: An elusive intermittent bug that is hard to reproduce or pin down.

   Example: "The login failure was a phantom bug until the team finally correlated it with one specific carrier network and a stale retry token path."
