The unmistakable vibe someone gives off when they are running on fumes — slow movements, monosyllabic responses, a thousand-yard stare, and a kind of resigned acceptance that the rest of the day is going to be a write-off. Knackered energy is contagious and instantly recognisable. You walk into a room and feel it. It's not depression, it's not rudeness — it's just someone who has nothing left in the tank and isn't pretending otherwise. Often used to describe a group, space, or meeting that collectively feels drained.
