A WUB seemd to fit my expression, but what is one? And what is an AZN not. Sorry to get off topic!
WUB is baby talk for LOVE - as in "I wub you."
As for AZN, for as long as this forum has been in existence I've been wondering what that stands for. In the main smiley set, it's actually a hidden smiley that looks like this:
The developers have never explained it, but AZN in texting shorthand is short for Asian, so it may have originally meant that, and the ^'s in the abbreviation :
^-^
could represent slanting eyes - though I can't say the smiley itself looks Asian to me. To me, the two ^'s in the code seem to represent the raised eyebrows:
And in fact, the AZN smiley is used most often to convey a snarky mood, as represented by the raised eyebrows and the curled up lip. (Though even if at one time the smiley was originally meant as a representation of Asians and it's meaning has since changed, which I believe it has, I don't think it was ever meant to convey that Asians are snarky.)
