I never use it but what is worse than seeing it in every second posts is when people actually use it while speaking.

What? You seriously don't say "lol" out loud do you?

I used to for a month, it was a phase. I do say rofl out loud though, to my dog & my best friends. Not to any random stranger, thats social suicide.
