draw the long bow meaning in English

吹牛

We can not believe him because he used to draw the long bow .
我们不能相信他。
On the other hand he might be only bluffing , a pardonable weakness , because meeting unmistakable mugs , dublin residents , like those jarvies waiting news from abroad , would tempt any ancient mariner who sailed the ocean seas to draw the long bow about the schooner hesperus and etcetera
如果是这样，倒还情有可原，因为任何一个老水手要是曾经跨越大洋航行过，一旦遇上地地道道的傻瓜，即都柏林居民，就像那些等着听外国奇闻的马车夫，都会情不自禁地吹起牛来，说什么“赫斯佩勒斯”号125三桅纵帆船啦，等等。
