This is a forums based question, I really think we need more emotes, there is nothing in those five emotes that really have much meaning.
uses of current emotes=
Nes-here for use instead of a curse-word, mostly used by idiots for no real reasons.
ice cream-real above.
panda- sometimes used for sadness/curse word, but mostly an idiots for no real reason.
Cookie monster*- sometimes used in the noobish cookie joke, but may be used to express...something, unsure of, I bet multibly things
cookie-Noobish abuse tool, and for the idioitic cookie monster joke.
* if you look closely, it looks like he is wearing some sort of naruto headband around his neck, and I really wonder why?
We need more, actual emote, emotes.
