A caddy. In golf, a person hired to carry a
player's clubs, find the ball, etc. Outside of golf, a person who runs errands, does odd jobs, etc.
From the Bill Murray character (groundskeeper
Carl Spackler) in the 1980 movie "Caddyshack", "So I jump ship in Hong Kong and make my way over to Tibet, and I get on as a looper at a course over in the Himalayas. A looper, you know, a caddy, a looper, a
jock. So, I tell them I'm a pro
jock, and who do you think they give me? The Dalai Lama, himself. Twelfth son of the Lama. The flowing robes, the grace, bald... striking."
Since the intern was not
busy, I paid him $20 to be my looper for the
day. He picked up my dry
cleaning, washed my car and filed all my reports.
