I'm not sure I wish to use it right now because I don't know when English speakers do it. Something tells me that we Russians make this sound similarly as you do and in similar situations. It's called chuckling, right?In what context do you wish to write 'hehehe'?
I had to google 'be up on' to understand what you exactly meant. So now I can tell you that yeah, I'm not up on it either.GeneD, I'm not up on my Latin.
What do you think?
hehehe represents a fairly casual laugh. You find something only mildly amusing.
heeheehee could certainly be a cheeky or repressed laugh, as in your example with children.
hohoho represents a belly laugh. Like how Father Christmas does it.
hahaha could represent a wide range of laughs. Perhaps this is the most generic of these four.
