Oi cunts! Seems to fit everyone...

"Sup Fuckers" is my go to.

The south, interestingly enough, always got it right: “Y'all."

Sup fuckers and non-fuckers (ace inclusion is important)

Ladies, Gentlmen, and other androgynous creatures (odo)

Alright losers listen up!

Comrades!

"Sup dudes" is what I use. easier.

edit: if there's any confusion, always defer to the philosophy of Ed from Good Burger.

"I'm a dude. He's a dude. She's a dude. Cause we're all dudes! (hey!)"

My manager says "hello kittys", that one is excellent because it weirds everyone out. Especially in a button-down corporate environment.

Guys, gals and nonbinary pals

"What up, dipshits?"

Bitches, bros, and nonbinary hoes

Greetings, citizens of earth

"Greetings, programs!"

"Neigh/Them" pronouns.

Alrighty campers

Esteemed comerades...

"Citizens"

UGLY BAGS OF MOSTLY WATER

No brownie points for guessing my preference here. Flawless, indeed.

I like the moderately-formal one from Dragonball Z Abridged: Ladies, Gentlemen, and the Technicolor Rainbow In Between!

I learned one from a Tom Lehrer concert decades ago (I wasn't there -- it was a recording)

"As Malcolm X was fond of saying 'Good evening to my friends and enemies. I say that because I can't believe everyone here is my friend, and I don't want to exclude anyone'"

Im a fan of "Team" in a business setting.

Negative, I am a meat popsicle

I find "hello, fellow kids" is what keeps me in with the hep crowd.

I like "ladies, boys, and ladyboys" myself, but I value comedy over being inoffensive.

"Alright you 'orrible lot!" has been my go-to. But I'm partial to "Hey Nooblets!"
