隨興英語 (001) - 【when pigs fly - 無稽之談；永無可能；絕不可能】
This expression means “never” because pigs
will never be able to fly. So if someone asks you when you will do something
and you know you will never do it, this expression can be very useful.
When we want to say that something is never
going to happen or that we have no intention at all of doing something. For
example:
I will trust you when pigs fly. 我絕不會相信你.
She will do that for you only when pigs
fly! 要她為你做那事是決不可能的！
A: When are you going to finally go out
with me?
B: When pigs fly! I’m never going to be
your girlfriend!
