Let's take rubber necking, for example.

以“引（rubber necking）”为例。

Baffling, right? We were necking like a couple of hooligans under the school bleachers.

很莫名其妙，对吧？本来我们还像在学校看台下的小流氓们一样我我。

But people still know what you mean if you say you saw a couple necking in the woods.

但当你说看见一对情侣在树林里深情吻，人们还是懂你是什么意思的。

Rubber necking is when drivers slow down on a road to look closely at a wreck or something else eye-catching as they are passing.

“引”指的是路上司机经过车祸（wreck）或是其他引人注目的事物时，将车辆减速以仔细看的行为。
