I dont know when this feature came on Yahoo messenger. Though I’m pretty often use Yahoo messenger, i usually dont pay much attention on emoticon. I rarely using it.

Hidden emoticons are emoticons that are not listed on Yahoo messenger window. If you are bored with the common emoticons listed, you can try these hidden emoticons. I see some of them are really funny, i dont know why Yahoo decide not to list them in the Yahoo Messenger window. May be they know that mystery and curriousity are sometime more attractive. Below are list of those hidden emoticons
