Peeps

Whenever there's any question, I usually open with "sup, dogs" in my most serious voice, then continue to deadpan refer to everyone as dog, such as "and you, dog, I need to check the grist mill, thank you dog". Fifteen years in and no complaints so far.

Friend

I've started using "hello chums"

Chooms

i find myself using "friend" a lot lately. dunno if that's a great replacement.

Earthling...Terran - I don't care how awkward it sounds. It's awkward for me to change might as well make it awkward for everyone.

Edit: just me being cranky... Normally I go out of my way to make people feel accepted.

I sound even more southern than I am because I say "y'all" frequently to avoid gendered pronouns. People, you, and we are often good. I think my favorite is "you folks".
