I see no explanation of the name on the site in the documentation, but there would be two origins that come to mind immediately:
- The japanese (romanized) spell of "bloomer", the garment, which is a well known cultural artifact, also famous in the manga/anime circles. It was removed from public school decades ago and stays in public's consciousness as an attire to wear mainly for porn, gravures etc.
- the DragonBall character named after the garment.
None of these two feel right in a corporate setting, and while a project name isn't everything, there's a myriad of other similar pojects out there with more recognition so the competition is tough.
It could enough for it to be only ever seriously checked in companies that are already past the point they care about any public image.
