Pop-up retail, also known as pop-up store/shop or flash retailing, is a trend of opening short-term sales spaces popular in America and Europe.

“快闪商店”（英文表达为pop-up retail或pop-up store/shop或flash retailing）是在短时间内开张的一种商店，在欧美很流行。

A pop-up retail space is a venue that is temporary: the space could be a sample sale one day and host a private cocktail party the next evening. The trend involves "popping up" one day, then disappearing anywhere from one day to several weeks later. 

“快闪商店”的店铺是临时租用的，今天这个店铺在做样品特卖，明天晚上可能就在举行私人鸡尾酒会了。某一天突然开张的“快闪商店”，在一天或几周后就会消失得无影无踪。

They are often used by marketers for seasonal items such as Halloween costumes and decorations, Christmas gifts and Christmas trees, or fireworks.

“快闪商店”通常卖季节性物品，如万圣节的服饰和装饰品、圣诞礼物、圣诞树，或烟花之类。
