Emo-ticons

Google chat has all these "secret" animated emoticons like a monkey face and a smiley face with a moustache, but the really vexing one is the "Rock out!" emoticon which makes an animated hand doing the devil horns when you type \m/.  Yes, it's quite clever in terms of arranging keyboard symbols and letters into a pictogram (as clever as "BOOBS" on a calculator), but how has the need to express "devil horns" become a more relevant need in IM communication than "8=====D" ?  Google people, get ontop of this. I'll be here waiting with my safesearch off.
