New emoticon

I am a fan of emoticons. That may surprise some, as I am, after all, the Punctuation Queen. But I think that emoticons are nothing more than additional and updated punctuation marks. Having said that, I would love for someone to come up with one that conveys a bit more contempt than :p. I mean sometimes you just need make sure your reader knows that you are really dripping with sarcasm. Anyone got any ideas for a great "sneer"????
