星期胡子英语怎么说

"Five o'clock shadow" 是指胡子长出来后留下的短毛，通常在下午五点左右出现。这个说法源自于男性在早上刮胡子后，下午五点左右胡子又长出来留下短毛的现象。
例句：
He had a five o'clock shadow even though he had just shaved that morning. 他早上刚刮过胡子，但是下午五点左右就长出了短毛。
She didn't like the look of his five o'clock shadow, so she suggested he shave before their date. 她不喜欢他长着五点阴影的样子，所以建议他在约会前刮胡子。
