According to a website I just found, The Unofficial Smilie Dictionary I could use
;-) Winky smilie. "I just made a flirtatious and/or sarcastic remark," a "don't hit me for what I just said" smilie.
0r :-> "I just made a really biting sarcastic remark"
Perhaps if I search I can find a really good tongue in cheek smilie icon
But they are not fonts
