To chase, harass, or drive roughly; to move quickly or to worry someone persistently.
Variant spelling of chivvy, from a historical event where British soldiers chased enemies at a place called Chevy Chase (Anglo-Scottish border), evolving into a verb meaning to harass or chase.
The word 'Chevy Chase' was so famous for a dramatic battle that it became a verb—kind of like how 'google' became a verb, except this happened 600 years earlier!
