Calling someone 'jumped-up' means they're acting more important than they really are, often behaving arrogantly despite not having much real authority. Think of it as someone who got a tiny promotion and now acts like they own the place. Itβs like a small dog barking loudly to seem bigger. Unlike genuine authority earned over time, 'jumped-up' status is often perceived as undeserved and flaunted to compensate for insecurity. They might be a bit over-the-top and try to show off their limited power. It implies a lack of humility and a tendency to overestimate their position.
