看著迎面走來的熟人，招著手、張著嘴，可就是叫不出對方的名字？嗯，這是明顯的“腦抽”癥狀。快看看英語怎么說！

Brain fade refers to a temporary inability to concentrate or think clearly. When your mind just goes blank, or when you know the answer but just can't say it, you are suffering from brain fade.
“腦抽”指短時間內無法集中注意力或者清醒思考。如果你大腦一片空白，或者明明知道答案卻說不出來，那么你就是“腦抽”了。

For example:

Prime Minister David Cameron blamed brain fade when he accidentally announced his footballing allegiance to West Ham United rather than Aston Villa.
卡梅倫首相說，他誤把自己支持的阿斯頓維拉球隊說成西漢姆聯隊，這全是腦抽惹的禍。
