everything you can possibly want, have, or do in a particular situation

When I was little, my family always had lots of pets - dogs, cats, hamsters, fish, rabbits - the whole nine yards. 我小时候家里总是有许多宠物：狗、猫、仓鼠、鱼、兔子，应有尽有。

The weather was terrible but I wanted to go the whole nine yards and get to the top of the mountain. 天气糟透了，但我还是想咬咬牙一路登上山顶。
