An old boss of mine started most group conversations with "right then you cunts..." and it was set the tone straight away. No bullshit, no egos, and no dragging on the conversation. Top fella actually, one of the best leaders I've had. We were his cunts, and he was our better-paid cunt.
We had another bloke who was a proper cockney boy. If you were in his good books, you were a "geezer", and if you'd ruined his day then you were a "slaaaaag".
I'm guilty of addressing my squad from my very junior managerial position as "alright my dudes", which on the surface of it sounds very male-leaning, but I think since the 90s "dude" has become as gender-neutral as they come.
That, or you could go full Karl Jobst and kick off with "hello you absolute legends .."
I call everyone nerds, and yall may think, not everyone is a nerd. Wrong.
Remember that jock from the football team, ask them about about sports betting. You will get a better lesson in sports statistics than you would by taking a college class. Everyone is a nerd about something.
You count every single protein you eat to get swole? Nerd.
You strap hard rate monitors to yourself to run a 10km? Nerd.
You go to concerts of your fav rapper and buy and wear his merch? Nerd.
You don't do anything that's interesting, but go to the screws and bolts plant every workday at exactly 6:30, wear the same blue dungarees, get off at 15:00, wash your hands with your favourite extra strong, lemon-scented, degreasing soap? Nerd.
You know which grain of wood you can glue together and which way it should curve to not trap moisture and rot? Nerd.
More comprehensive, yes. But everything will only superficially resemble probability (or worse, statistics), without any idea zeroing on the real thing.
Alternatively, you can ask a crystal-hippie about quantum mechanics. Oh, well... we have LLMs nowadays, you can ask them anything.
Man, (neutral), southern is preferable for usage of y'all, but most people can pull it off. Edit: somehow forgot to type the most important part. Have some god damn faith.
Risky joke - could get a laugh, could get you a meeting with HR without biscuits. It's worth a punt though if you know your audience!
If you make the joke a bit more explicit it tends to get a few more laughs, like "this one goes out to the tireless administrators, creative engineers, fantastic embeds... and Paul".
Only pull those stunts if you're happy to get the piss taken out of you in return though, else you'll look like a right tosser.
Oh, man, I'm pretty decent at this. Man is a favorite of mine. You may be thinking "that's not neutral". To that I say, yuh huh. Pardner, obviously said in some kind of Arthur Morgan impression (quality irrelevant). Buddy, if you want to be dismissive, as in "Yeah, sure buddy". Bitch, to be used with close colleagues. Also somehow gender neutral. Diva is pretty universal. It has the added plus as a quick little homophobia check. Girliepop, similar usage as diva. Pookie/ pookie bear, to be used with close friends and partners.
