It's been over a year since FiTR embargoed the use of the term "gutbomb" on our website, except for special cases. This is one of those special cases. This post seeks to define gutbombs, note how and when they occur, and offer a selection of recently encountered examples. Perhaps it will help you avoid G-bombs in the future - or maybe it will just induce you to try new ones. Each example is embellished with FiTR's 100-point Gutbomb Index (GBI).
