Now this is not quite as negative as cheapskate and tight arse.

这个习语没有 cheapskate 和 tight arse 那么消极。

If someone is stingy with their money or maybe they're quite obsessive about avoiding to spend money, then you could call them a cheapskate or a tight arse, but don't say it to their face.

如果有人对钱很吝啬，非常执着于避免花钱的话，那么你可以说他们是小气鬼或吝啬鬼，但不要当面说。
