- 1呆瓜、笨蛋（美式口語，多半是笑罵，不是很重的髒話）
A doofus is a stupid person — someone who has just done something or silly. It is American, informal, and quite soft. Friends call each other a doofus when someone forgets the keys or walks into a glass door. It sits closer to “silly fool” than to a hard insult. You would not put it in a formal letter. Some people find it a little old-fashioned, but it is still said, often with a laugh. Though actually, it is almost always a person, not a thing, and it is not a school subject word. It does not mean dangerous or cruel; it means “not thinking clearly, just now.” Tone of voice does a lot of the work: said with a smile it is teasing; said with a hard face it still stings, but it is not among the strongest rude words. You do not call a clever plan a doofus.
組成Perhaps a change from earlier goofus (from the 1920s), with help from Scots doof, “simpleton.” Scots doof comes from Low German doof, “deaf,” which also had a sense “stupid,” and that Low German word is related to English deaf. Some people have wondered if dupe played a part too. All of this is a perhaps, not a sure story.
