One of the best types of lies are ones which make people want to stop asking questions all together. A good way to accomplish this is for the lie to be about something You Dont Want To Know
TMI lies are great not only because they cause the person questioning them to lose interest but they are a good cover up for suspicious behavior. Bob might be suspicious if Alice claims she snuck off in the middle of the night without telling anyone to get ice cream, if she claims she did so to replenish her tampon supply on the other hand there's at least a 9/10 chance that Bob will leave it at that.
"Womens problems" in fact are a very common TMI Liei. There is even an example of this happening in Biblical scripture, making this trope Older Then Feudalism

This was a factor in the Lizzie Borden murder trial. She said that bloody cloths that a witness had seen had been menstrual cloths (they didn't have disposable feminine products back then) and everybody involved with the trial all got squicked out over this discussion of menstruation and decided to just accept that explanation and move on so they wouldn't have to hear about it anymore.
In The Bible
, Jacob and Rachel flee from Rachel's father Laban, stealing some of his household idols as they go. Laban catches up to them and demands to search their tents for the idols.
