Mine is OOO for Out Of Office. I always misread it in my head like a ghost and it takes me a few seconds to process. It also doesn't translate to speech—you have to say the whole thing.
Interested to see if others have similar acronyms they beef with.
See, I feel like I have to do it to show some levity, since tone doesn't come across through text.
There's a big difference if you're talking with a friend about something stupid they did, and saying "You're such an idiot lol" and "You're such an idiot." One is teasing them, the other is chastising them.
If someone is doing that to you it means they don't like you or are otherwise done with your shit. It's also a way of saying "I really shouldn't be saying this" as kind of a way of addressing what you're said before is fucked up but insisting the need to communicate it regardless.
That's a bit annoying, but at least it represents laughing. What I hate is when it's just used to "lighten the mood" and doesn't represent laughing at all.
And, the proper way is "jajajaja", as my Spanish-speaking friends have taught me.
