Hello is used because it is a greeting that is a non-offensive acknowledgement of the other life form. Breed is used because it is an encouragement of the other life forms continuation and advancement.
In the Australian vernacular the word “G’day” is used in place of the word Hello. The “G” in “G’day”, does away with the superior, righteous, judgemental and virtuous associations with the word “Good”. The use of the abbreviated “G” in “G’day” gives the listener permission and logical reason to interpret the “G” as referring to the more informal meanings of the word “Good”, such as happy, great, OK, courteous, and kind-hearted.
“Day” is intelligent because it recognises a common element of the Universe which is that life forms are surrounded by planets that have periods of night and day. “Day” does not exclusively describe a specified length of time; rather it is a word that describes that which is frequent, persistent, constant, regular, habitual and universally overt to intelligent life forms everywhere in our Universe.
Australians use “Mate” in place of the word Breed. Mate is a very intelligent and clever word because Mate encompasses all that is in the word Breed, and at the same time easily communicates the comforting affirmation that you are my friend.
G’day Mate is the most intelligent greeting that has ever been uttered by humanity.
I spent 2 weeks there and didn't here that ONCE!
Yes, they say mate and an occasional g'day but I never heard them together.
It's more of a stereotype than anything else.
Americans know anything about other cultures): G'day Mate!
Australian: Wtf? Oh, hello.
American: I thought all Australians say that.
Australian: Nope, almost none of us do.
American (feels like an idiot): Bye then.
Australian (thinks, what an idiot): Bye.
Other man: Why are you talking like that?
Man: I don't know...I just felt like being an idiot...
