We use it a lot as a noun. He's such a showoff. You can also show something off.

我们经常使用它的名词形式。他是个爱炫耀的人。你也可以炫耀某物。

And you know, in part two I believe that it's the real showoff if I can say so.

我觉得第二部分是秀口语的时间，如果我可以这么说的话。

If you're doing well, how do you let that be known without being seen as a showoff and a jerk?

如果你做得很好，你如何让别人知道你的表现而不被视为炫耀和混蛋？
