I'm an excessive gravitas person. Instead of laughing, I just narrow my eyes and glare at you in silence.
The wind dies. Nearby plants wither. Small children hide.
I usually use "hehe" to express a more sheepish laugh
"Haha" for a more normal one
And "Hoho!" For a surprised/exited
I know this girl who NEVER laughs. She just deadpans "I'm dead." I'm fucking hilarious, and it gives me low self esteem to hang out with her so I stopped. Now me and my real friends laugh about it.
Anyway I say "hoo hoo"
I used hehe a lot at one point, but it's so uncommonly used I go with haha when I mean hehe.
Hehe just makes me think of Michael Jackson so I say haha. Hehe if I’m trying to be Michael Jackson
