lol or lmao but it doesn't mean i'm laughing it just means i'm suffering ........ lol............ i guess if i think something is funny 4 Reals i'll say hahah but uhhh sometimes i write "hahah" just because something is like ... really awkward. . ... and not actually funny.. so idk.
I use both, although I'm more likely to say "haha" more. I use "lol" more for things I find hilarious, while I use "haha" for things that make me feel embarrassed.
I don't really say any, it depends who I'm talking to, if its someone I don't know that well I'll say "hahah", I think I say that to my family too because they say it but I don't like it much. To my friend I'll say "laughs" and recently "lmao" even though we used to say that like 4 years ago then stopped. To me "lol" is usually the most sarcastic thing evee.
I use both but most often lol, and haha if I already used lol before. I need to learn how to word my sentences so it won't seem cold without adding emoji/lol...
I'll use either depending on which seems to "fit" better at that particular time. Though I tend to only use lol when chatting very casually or to particular friends. It's not a standard part of my vocabulary in the way that haha is, really.
I do haha. I feel like lol has lost it's meaning and now is a sign that the person using it is not actually laughing but doesn't wanna hurt your feelings.
