I don't want to be the third wheel.
我不想当电灯泡.

========================================

一般的自行车都只有二个轮子, 要是有三个轮子呢? 没错, 那第三个轮子就是多余的. 所以 Third wheel 就是美语中电灯泡正确的表示方法. 还有一个讲法, 叫 I don't want to be the third arm. 这里不是说 "三只手" 的意思, 而是和 third wheel 一样, 都是电灯泡的意思.

I don't want to be the third wheel

I don't want to the third wheel.

I don't want to be the third wheel.
我不想当电灯泡.
