A bacronym is a reverse engineered acronym. The idea is you find a name for something and to help sell it to the approval committee you create an acronym as an afterthought, buttressing your argument for the name. Nobody ever remembers what the bacronym stands for, but no matter. The audience it is created for is strictly internal and only for buy-in.
An impessively inane example of this is ‘Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism”, aka the USA PATRIOT Act.
It’s true. Because Asinine Consultants Rely On Nattering Yes Men.
