I stumbled upon some instructions for getting secret Skype emoticons today. To unleash them on your unsuspecting contact list type one of the following, or for that matter all of the following if you are feeling a bit excitable.
(mooning) (kate) (finger) (bandit) (toivo) (headbang) (smoking) (rock) (drunk) (flag:GB)
Most of them are more or less self explanatory so I won’t bother. And to give credit where it is due I found them here.
Happy emoticoning :)
