Ratting on people, or tattling on them, will not win you friends. It just makes you a rat. Or worse -- a rat fink.

出卖别人或是打别人小报告（tattle on）人是不会有朋友。会让你成为一个不被信任人，或更糟，一个卑鄙小人（a rat fink）。

Any finks drift along I'll know them and the rest of the crowd is watching those numbers and nothing else.

任逐流怪人我都会认识他们， 其他人看些数字， 别无其他。

And similarly with this one: " fink" , " I fink" .

与此类似：“fink”、“I fink”。

Now there are some parts of the UK where it's more common in the dialect and the accent to say " fink" instead of " think" .

现在在英国一些地方，在方言和口音中更常说 fink 而不是 think。
