笨蛋的英文单词读音应该是[diu sh bag],我也不知道自己读的准不准,但是完全找不到这个单词,大概就是笨蛋,垃圾,

dooshbag
The proper way to spell this word is "douche" bag. As every knows, a "douche" is a vaginal cleaning. Hence the word "douche bag" relates to a dirty, fetid, lowly, or stupid person; an ignorant derelict.
Stop wasting time, DOUCHE BAG.
