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.


Jayne: Hey, Sara

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

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.

Well, knowing that anyone in their right mind wouldn't look up "Hi" in the U.D., I can safely assume you did it for one of these reasons:

1) Your parent/roomate just walked in and you were looking up something that was very innapropriate for the time being.

2) You were just masturbating to some of the free erotica on this site, and in that case, just go back to what you were doing: sex story.

3) You aren't in your right mind and should go see a therapist.

4) You are extremely bored.

5) You are an alien from a parallel universe and would like to study the various aspects of human culture. One of them being the complex greeting system.

6) You tried looking up ho or bi but misspelled it.
Person 1: "So I was like looking at like this thing on UrbanDictionary last night when my parent walked in. I like typed in 'hi' and when my parent asked what I was doing, and I told her I was looking up 'hi' on UrbanDictionary. She then looked at my history and saw that I looked up 'tramp.' It was so hilarious the look on her face!"

Person 2: "ZOMG!! That's so ridiculous. I would have gotten grounded!"
