A whirling dervish is a member of a Sufi religious order who performs a ritual dance involving spinning continuously. It's also used metaphorically to describe someone who is constantly active or in a state of frenzied motion. Think of it as someone who is always buzzing around, never still. Unlike someone who is calm and collected, a whirling dervish is a whirlwind of energy. The term implies both spiritual devotion and frenetic activity. It's a vivid image of constant motion.
