Loop

Definition: "Loop" refers to one circuit around the golf course, 18 holes. It is most commonly used by club caddies to refer to the number of times they worked in a given day. For example, if a caddie said, "I did two loops today," that means he carried the bag for one golfer, then, when that round was completed, he went back out again with a second golfer for a second time around the course. This also explains why caddying is sometimes called "looping."
