Morphology

big + boy

The meaning is directly built from 'big' (older/larger/more mature) + 'boy' (male/young person), so a B1 learner who knows both words can readily infer either a physically large male or a figurative sense of someone more mature or newly independent. The playful, extended sense ('big boy now') is a predictable pragmatic extension and mirrors patterns found in many languages, making the expression transparent to learners.

Etymology

Big boy comes from the simple image of a child who looks taller or does a new grown-up job and adults say big boy to praise them. That's why big boy is used today to mean someone 'grown up' or 'responsible' in a friendly way.
