高峰期地鐵到站時，我們通常是裹在人流中不由自主地往前走，這時候前方有個人努力地排除萬難向地鐵方向擠過來，不顧眾人的目光，這就是subway salmon——地鐵三文魚。

Subway salmons refers to the one or two people who insist on going up a stairway or down a stairway (usually after a train arrives at a subway stop) while all the people leaving the train are going in the opposite direction.

地鐵三文魚指的是地鐵站里（經(jīng)常是地鐵到站后人大量涌出時）堅持逆著人流上下樓梯的一兩個人。

Example:

"Of course there were subway salmon when I was late for work and I was trying to get out of the subway in a hurry ... Dude, couldn't they tell the train already left?"

“上班遲到想趕緊從地鐵里出去時總有‘地鐵三文魚’……老兄，難道你看不出地鐵已經(jīng)開走了嗎？（還擠個什么勁啊）”
