疯狂星期四用英语怎么说

"Crazy Thursday" in English is commonly referred to as "Black Friday". It is a term used to describe the Friday following Thanksgiving Day in the United States, which is typically one of the busiest shopping days of the year.

The origins of Black Friday can be traced back to the 1950s, when retailers began using the term to describe the day when they would go from "in the red" (losing money) to "in the black" (profitable) for the year. In recent years, the term has also been used to describe the start of the holiday shopping season, with many retailers offering special deals and discounts on this day.

Example:

"I'm going to the mall on Black Friday to get some great deals."
"Black Friday is the busiest shopping day of the year, so be prepared for crowds."

翻译：

"我要去商场在黑色星期五买一些优惠商品。"
"黑色星期五是一年中最繁忙的购物日，所以要做好拥挤的准备。"
