I am not partial to informal nicknames. If I stand with a group of my male coworkers I usually greet them with “gentleman” or something that. I don’t work with a lot of women but I’m not sure what to say to a group of women. Ladies seems kind of demeaning and gentlewomen sounds weird to me. I usually just go with miss or ma’am.
Having come up in the 90s-00s, the few times I've been called "daddy" were a little surprising at the time ("it's just something I say, don't overthink it", etc), but thankfully said moments were in the rear-view quickly enough.
In later years, my kids didn't add the "y" and one even asked why other kids say it that way. Hell, I'm ok with "dude" from my kids or their friends, in certain contexts, but "bruh"? Might as well try calling me "son" or "boy", and see how that flies, child. 🤪
