Mine are "lol" and "lmao". I get what they originally meant, and I get why most people use them nowadays. It's just that they often signal "I have nothing to contribute, but still expect people to read my crap".

As a second (third?) place, "WYSIWYG". If you're going to coin such verbose acronym, might as well sub it with an actual word, like, dunno, "transparent".

EDIT - "lol" = "lots of laughs", "lmao" = "laughing my arse off", "WYSIWYG" = "what you see is what you get".

EDIT2: as another poster correctly pointed out, "lol" also originally meant "laughing out loud". Perhaps even more than "lots of laughs".

My least favourite acronym:

• AUTMA: Americans use too many acronyms

What, no votes for 'goatse'?

I'll uh show myself to the logout button now

IKR required a search to figure out. Autocorrect takes care of these typical phrases. Imo the only one I like to use is imo for some reason.

I hate LFG because gamers can't agree on how to spell it or what it means... Sometimes it's spelled LFP, LFF or LFM... And sometimes it means "Looking for Guild".

Worst: TLA

Best: WOMBAT

Like all of them, I never remember what they mean and there are some people at work who love to use em. It just makes meetings take longer and emails become less legible.

ICYMI (in case you missed it) and IYKYK (if you know, you know) which frequently get crossed in my head
