Hi

When a fucking person greet you, idiot.

Hello and Hi are the same thing by the way, if you are that fucking a idiot.

Hi-Hi

When a very bubbly or happy person is in a good mood and wants to greet you in a special way.
Sara has just gotten an "A" on her essay and she walks up to her friend, Jayne.

Sara:Hi-Hi!!

Jayne: Hey, Sara

And the two friends walk away with Sara blabbing away happily.

hi hi

radio term

ha ha (laughter)

"hi hi" is the Morse equivalent of a laugh as in Morse it sounds like someone chuckling ("hehhehhehheh hehheh"). That is ditditditdit dit dit --- or dot dot dot dot dot dot. You really have to listen to it sent in Morse to appreciate its laugh like sound. It is most commonly used in CW (Morse Code), but has carried over to voice as well. Many CW expressions have carried over to voice -- such as 73 (Best Regards) and 88 (love and Kisses), etc. The origin probably dates back before radio to the telegraph days. And since Hams used Morse long before voice became practical-- the sound of the Morse characters HI HI was used to resemble a laugh sound. In some sense it is equivalent of a smiley. It's onomatopoeic -- that is the naming of a thing or action by a vocal imitation of the sound associated with it (as buzz, hiss) The definitive answer might be found in the "Dodge's The Telegraph Instructor Manual" circa 1850 to 1900. However, I have never been able to find a copy of this document. Wish I could as it would help to see the transitions from telegraph to radio usage.

hi

The greeting word you use when some has said "hey" but you don't want to say the same word so you say "hi" instead
a person you know: hey
you: *types hey* *then realizes that they've already said that* *slight panic* *erases hey from vocabulary* *thinks for 2 seconds* *plays it cool by typing "hi"* *waits couple minutes to send* *sends text* *thinks crisis is averted but knows that this will only keep happening* *cries inside* *question life choices* *walks out of room and talks to people* *act as if you good when really you know this dilemma could've gotten you killed* *sip drink*
