you're right. lol = haha ( ฮ่าฮ่า ) or hehe ( อิอิ)

lol what's "อิอิ".. it's like a laugh or something, right? well, for expressing laugh in thai, we often would use: หุๆๆ ฮ่าๆๆ อิๆๆ and so on....... and those are just the same as ( LOL=laugh out lound as in english)

Besides, I think that 'อิอิ' is much proper for the shy or woman laughing. If you are man, it should be synonym to 'หุหุ', I also use that sound. However, that's not a big deal, isn't it? หุหุ

It's kind of quiet laughing, Moreover, it sounds like it's just OK, not really funny though. If you think the content is really funny to you, you better use '555' instead.

ahh i thought so.. thx ^^
