"Lol" is definitely overused in mostly chat conversations, so this brings up the question: do you laugh out loud when you type "lol"?
I tend to type "lol" a lot, even if I'm not really laughing. If the person isn't talking about a topic not comical, sometimes I'll say "lol" just because I have nothing else to say. If I'm really laughing, I'll emphasize it with capitalization. I rarely type "rofl" or "lmao" but if it was really that funny I'd probably capitalize "lmao" and use that.
