Interesting question!

I hardly ever curse out loud, but seem to be a lot freer with it online, lol

This isn't exactly what you were asking but a couple of times, I've used net lingo in RL, like telling the boss "brb"... argh!

hee hee! That video made me ROFLMAO!

Now that's a good trick, say the full thing in your mind so you don't make a mistake in rl, I mean real life :P

I just know I'm going to slip up and say *hugs* sometime to the wrong person....

I've found that certain people talk like they write...Most of those people I've found also happen to be women...At least, that's been my observation...I don't know why...

I have a tendency to switch: to write like I talk and then write like I think, which are sometimes two diametrically opposed processes...I find most men write like they think or write with a goal in mind...

And as for the usage of "y'all": I use it alot...I have an affection for the word (despite most white northerners' snobbish attitude towards it) and I feel it's a useful word, since there isn't a plural form of "you" in the English language...

but... but... "y'all" is a contraction of "you all" which IS plural!
I thought "y'all" was "you all" and "all y'all" was "all of you all" so different levels or emphasis of plurality, like "them" and "all of them"

y'all is the same for me. And 'dude' as well. I don't think I've ever actually said dude to someone but I use it quite a bit online.

me three!

Hm... I was going to say OMG, but I do say that in conversation. :{

I can't really think of any words I use online that I don't in reality o.O

I say that too! XD *geek*

Hmmm that one MIGHT work. I do cackle evilly but probably not exactly like that!

:)

oh, I do. It helps to have a deep bass rumble to it.

the use of y'all online is simply your inner Firefly being set free. It is very shiny.
