OK. When you can't do something that you want to do because of some reason, some obstacle in your way, then you're snookered.

好的。当你因为一些原因、一些障碍而不能做你想做的事时，你就是处境困难。

And it comes from the game of snooker because if a ball's in the way and you can't get your ball in the hole, then you're snookered. - Got it.

这个词来自斯诺克比赛，因为如果一个球挡在某处，你不能把球打进洞里，那么你就是遇到了障碍球。- 明白了。
