Morphology

ball + of + fire

The components cue a metaphorical reading: 'fire' readily evokes energy/passion and 'ball' suggests a compact, intense unit, so a learner who knows the words could partially infer that it describes strong energy. However, mapping that image onto a person ('very energetic') is a conventionalized metaphor and not fully predictable without prior exposure, and similar constructions are not uniformly lexicalized across languages.

Etymology

Ball of fire may come from the picture of a small bright ball of fire that moves quickly and burns with energy, like something full of life and action. So the phrase is used for someone who is very 'energetic' or 'dynamic'.
