I’ve always considered that texting “hehe” is a light chuckle, a “heh heh” sound; “hehehe” is more of a giggle, whether coy or creepy; and any more “he”s than that delves into witchy cackling territory.

In contrast “haha”, “hahaha”, and “hahahaha”, all sound the same in my head, and the meaning only varies in intensity but is more context dependent.

heh - slight laugh
hehe - mischieveous
hehehe - genuine laugh
hehehehe - Lois, this is Family Guy

By number of 'hehs':

1-2: situational ranging from genuine to sarcastic to 'funny but not haha funny'

3-4: "got'Em"

Hehehehehe: devious

Anything past that is a chuckle on its way to laughing.

Muahahaha!

Hehe: innocent little chuckle

Hehehe: mischief

Hehehehe: devious plotting

"Hey Lois, I'm text based!"

tee hee :3

Hehe in any form sounds like Michael Jackson in my head.

I think that typing "hehe" (or any of its variations) is like saying "gasp" or "shudder" out loud. Gonna take what you have to say a lot less seriously after that.

I agree on the first part, but disagree on the second.

haha is more like saying it without changing your facial muscles. hahaha is then the normal laughter and hahahaha is the crazy psychopath, let's back away fast with more ha' equaling to more running speed.

Whimsy? On the internet? Why, it's unheard of!

one is mike jackson, one is a cute giggle, the last one is a sociopath

this should answer your question

Best one, by far (that I never use): Ha!

Thanks… Now you’ve got me thinking about /HAAW/.
