Some genius at one place I worked decided to call our new SIEM offering 'INASS'. They were completely serious. Company head didn't see anything wrong with it, so for a few months we were offering INASS as a service. Can't remember what it stood for now, but luckily one of my higher-ups got them to change it to something more reasonable.
Yeah, I had to leave a few meetings to 'get a drink of water' when we were discussing this. I wasn't the only person in the room who did. We got a lot of odd looks from seniors in that meeting. Perhaps it's only a millennial thing to find SIEM INASS funny?
I once headed up the As-Supported Structure team, and a friend of mine got to choose his own team name so he called it the Technical Information Team.
This whilst we were working on a product called the A????????? [0] Information Delivery System. We actually laughed on the conference call when they told us but they weren't joking so someone had to use that super-polite voice you use when telling your boss he's been an obvious moron and explain.
You can be professional and have fun at the same time. (Or at least most Google engineers believe so.)
