Cutesy names for your employees/coworkers always comes off as creepy and cult like to me. Huge red flag when choosing where to work.
It's a bit David Brent/Michael Scott, probably quite well meaning but a bit off.
I agree I hate it, but there are some companies that do it more jokingly than others.
Personally I avoid companies that talk about "culture" ad nauseam.
I love working with other people, but NOT under those circumstances!
