lol is overused, if people were laughing as much as they say then we have a lot of psychotic people around. Think about it,
"Hey what's going on?" "Nothing, just hanging around" "Me too lol" "ha ha, me too, lol"
Really? laughing out loud? Really? Are you? If that were real life would you really be laughing? If you were I'd be a little scared to talk to you.
That's why I like loti, laughing on the inside. Because face it, that's what you're most likely doing.
