Her insults rolled of me like water but the shit hit the fan after she claimed to possess information leading to proof that my Mother wore Army boots.

Shit Hit The Fan
The situation where a recent catastrophe is further complicated by some application of Murphy's Law or further revelations. Taken from the mental image of the "fragrant and pictorial" mess that excrement would make if it came into contact with the blades of a fan...
The shit is information, and the fan a person or persons (often an employer or partner or someone in a position of seniority or superiority) to whom the information will be viewed as very bad news and also who is/are going to react immoderately and with no concern (or even some delight) as to whom the information then spreads.
This is an analogy for the worst possible development where concealment or deception have taken place and is a story in three parts: 1)The shit and the fan are seen as separate giving rise to nervousness of the awful consequences should they meet. 2)That moment arises, when time appears to stand still and the blades of the fan appear frozen for a split second. 3)There is an awful smell and a heck of a lot of clearing up to do.
When a situation goes from bad to worse. Could be just about any situation work related, family related or significant other and so on.
When we were running late for our friends wedding because of me i was in trouble but it wasnt til we made it there that the sh_t hit the fan, the wedding was the previous day.
The point at which "the shit hits the fan" is the point at which an already unstable situation devolves into utter chaos, often in spite of--or even due to--a higher authority's attempt to control it.
Basically, this is when emotions break loose and people get hurt. A literal meaning would be that shit gets on everybody due to the intrinsic nature of the fan.
