ROTFLOL.
You know people say that but they're not really rolling on the floor laughing out loud. So why say it? *shrugs* who knows. Kinda like the "How many licks does it take to get to the center of a tootsie pop?" I don't know. Neither am I planning to try. You know those people that know? Yeah, they've got too much free time. :P

That could mean two things. "Laughing out Loud" or "Lots of Love" Your choice. Although nowadays, it means neither. It's more of..."I have nothing else to say." DON'T DENY IT. You know it's true. I use it too much when I'm IMing or Iris Messaging (only PJackson fans will understand that). Lol. <------ See?

Talk to you later. What if it's not later? Whatcha gonna put then? TTYT? Talk to you tomorrow?

When people say that, they usually don't mean it. They actually mean, "Be right back cause when I come back, I'm going to leave." Yeah, that's right. I mean sometimes it even means, "I won't bother replying for another day." People, don't say BRB and just leave or not reply. It's annoying.

It's not that hard to just say ok. It's still two letters.
Okay, that's all for my chat speak rant.
