I'm not sure specifically what a 'ball pressed wife story' is as it's not a common or known phrase. It could potentially be a very specific or made - up story within a certain context, or perhaps it was misphrased.
It might be a very strange or unique story. 'Ball' could refer to a variety of things like a ball in a game or some spherical object. 'Pressed flat' is an action description. But without more context, it's hard to say what the 'wife' has to do with it all in this 'story'.
There are so many possibilities for what the 'ball pressed flat wife story' could be. It could be a modern - day story where a ball used in a sport, like a soccer ball, gets pressed flat by a heavy object. The wife might come into the picture if, say, her husband was the one who was supposed to take care of the ball, and now there are consequences for the flattened ball. Or it could be part of a children's story where the ball is a beloved toy of a family, and the wife is the mother who has to deal with the disappointment of the child when the ball is flattened. Without more details, it's difficult to give a more precise explanation.
Since I have no prior knowledge of this 'testicle pressed flat wife story', it could be anything from a comical misadventure in a fictional setting to a disturbing account within a particular, perhaps very niche, genre of storytelling. It could also be a story created for shock value, but again, without more details, it's impossible to accurately describe what it's about.
There's no way to accurately tell what the 'ball slapping wife story' is without more context. It might be a story within a particular community or group where they use this phrase to refer to a specific incident or tale that involves some sort of slapping action related to a ball and a wife - like character in a fictional or real - life based scenario.
The 'ball stretching wife story' is quite an ambiguous title. It could potentially be a story told within a family or a community. For example, if 'ball' refers to some sort of spherical object in a household like a toy ball, and the wife is involved in stretching an activity related to it, like stretching a net around the ball. But again, this is all speculation without further details.
