Morphology

go + off + on + one

There is a partial clue in 'go' (to become) and the particle 'off' (sudden change or eruption), but the sequence 'on one' is colloquial and not compositionally predictable. The overall sense 'suddenly become very angry / rant' is idiomatic and especially British, so a B1 learner who knows the individual words would likely not reliably infer the full meaning without prior exposure.

Etymology

The phrase go off on one paints a picture of someone suddenly go off like a loud alarm and then start on one long angry or excited speech. So, the phrase means 'to suddenly become very angry or speak passionately'.
