I think we need some.
I'm not talking about our little chatspeak abbreviations, like HA or MCT, I mean real sayings, euphemisms, proverbs, etc.
For example:
"Oh my Kumoses!"
WIN. I love it.

I agree with everyone else on this one.
Though I've noticed that the filter has caused people (myself included) to say "What the love" in the real world.
I make a point of not using such phrases, because I don't cuss unnecessarily... (Meaning, I can in fact come up with a better way of putting it.) But this... This I love! -will use- XD
