haha decoded

1. ha = not so funny (maybe a slightly interesting comment was made, this can also be in response to a negative comment made about you. ex: Dude your a fuckin asshole - ha yeah well fuck you too dick)
2. hah = polite laugh
3. haha = funny, but just a little...it's a positive response
4. ahah = slightly funny (the reversed ahah shows a bit of speed on response indicating funnyness)
5. hahaha = funny (anything after 4 characters is a direct linear indication of funnyness)
6. ha ha ha = funny (either a sarcastic'ish response like the snl slow clap http://bit.ly/121qJD or similar to "ha" if $age > 35)
   
7. HAHAHAHHA = really funny (uppercase show you really mean it)
8. HAHAHSKDJFSLDJAHAHA = really funny (the random characters are added for showing you can't do anything but bang on your keyboard)
9. laksjdlahahahahHAHAHAHAAHA = really funny (and the lower case switching to uppercase shows your intent to get something back to them quickly and then you follow it up with the HAHAHAs)
