field day
Meaning
A time when someone has a great opportunity to enjoy themselves or to do something enthusiastically, often because conditions are ideal (sometimes by exploiting a situation).
Origin
Originally a literal “field day” was a day for military drills or exercises held outdoors; later it broadened to mean any special occasion, then figuratively an ideal chance to indulge in an activity or enthusiasm.
Notes
Somewhat informal. Means “enjoy/indulge freely” or “take full advantage.” Can be neutral/positive, but often implies gleeful exploitation (e.g., media mocking a mistake).
