What is the meaning of 水 in this text? Someone was asking about this in a German Chinese forum. Now I too would really like to know what 水 is here! The author is from 重庆， maybe it is dialect.

他一向说话算话，没有水过我，起码在这之前，他没有过，一定是他明白自己做的丑事——用那么一本诲淫的书，公然引诱一个处女，现在不好意思了，被我逮住了。

The situation is: the main character of the book is meeting her history teacher for the first time outside a hospital, he doesn't show.

So maybe 没有水过我 is 放鸽子 but how does 水 come to mean that??

In German it was translated as cheat = verschaukeln. The original questioner also mentioned 过水 www.zdic.net/c/7/1d/44699.htm 2， which I would loosely translate as 'he never fucked me about before'.

English from Howard Goldblatt: Always a man of his word, he'd never said one thing to me when he meant the other, at least not till now. He must have been ashamed of what he'd done - giving a virgin a dirty book like that - and knew that I'd seen through his little game.
It is dialect:


  　　水最大的特点是没有根基，喜流动。好个重庆城，山高地不平。水就更容易流动。天上一下雨，地上流成河。雨过天晴，刚才还流得像河一样的雨水，便不见了踪影。那雨水流到长江嘉陵江中，也不会停止脚步，继续流动，浩浩荡荡，汹涌澎湃，汇于朝天门外，奔向朝阳升起的东方。在重庆方言中，“水”的这种特性得到引申，得到凸现。
  
  　　“水”就是说话不算数，就是办事不牢靠。这事“水”了，就是说这事没有办好。
