I've heard it a thousand times. Can't you make up something new?

我都听了有一千遍了，你能不能弄点儿新的理由?

Do you think I could make up something like that?

你觉得我能编出来这种事吗？

The opposite of " real" in this sense would be " imagined" – something that is made up, something that you invented.

从这个意义上说，“真实”的对立面是“想象”——虚构的东西，你发明的东西。

The expression " to be a figment (figment) of your imagination" means that it's something that you made up, something that you invented, something you imagined that's not real – not true.

“成为你想象中的虚构（figment）” 这句话意味着它是你编造的东西， 你发明的东西， 你想象的东西， 但它不是真实的——不是真的。

So getting something like this it's hard to make up something that I screwed up the night before, partying too hard, or maybe we're just living a life of dream or luxury.

所以得到这样的东西很难弥补我前一天晚上搞砸的事情，派对太激烈，或者我们可能只是过着梦想或奢侈的生活。
