We watched him drink his pain away a little at a time
But he never could get drunk enough to get her off his mind
Until the night
He put that bottle to his head and pulled the trigger
And finally drank away her memory
故事主角"he"一直在酗酒,但是那啥那啥愁更愁,所问的那句把bottle比作gun来叙述,也就是说他喝死了.
嘛,本来就是歌词,有点修饰手法,或者隐晦的表达也很正常.
