: What is the etymology of the phrase "bats h i t crazy" or "bat s h i t crazy"?
: Does this have something to do with a malady afflicting guano miners?
: Or is histoplasmosis or nitrate poisoning involved?
Bats = crazy. Probably from the way they fly around in a seemingly crazy manner. I don't know how bat-sh*t crazy would have evolved.
