Slipshod work is done too fast and without care, and the word is never a compliment. A slipshod essay has messy thinking, missing steps, and mistakes the writer did not bother to catch. A slipshod repair looks finished from far away and fails the first time you use it. Teachers, editors, and bosses use it to show they are not pleased: the job was not just imperfect, it was careless. It usually describes work, methods, or habits, not a person’s shoes today. You can call a translation slipshod, a building plan slipshod, even an argument slipshod if the reasons do not hold together. It is fairly strong and a little old-fashioned in tone — not slang, more the voice of someone who expected better. Though actually, the picture hiding in the word is about shoes. Long ago, slipshod meant you were walking around in slippers, or in shoes that were only half on, looking untidy. From the early 1800s people moved that “untidy” feeling onto work and manners. So the disapproval is old, but the shoe meaning has almost dropped out of daily talk. Nobody looking at a slipshod report is thinking about slippers unless they know the history.

馬虎的、草率的（帶責備，不是「鞋子會滑」）
