*Whimper* You guhuhuyyyyyyyys...I am one bad night's sleep away from going batshit cray-cray! :( Going to put in ear plugs, crawl under the covers, and pray for the sake of all the brains in Eugene that I don't wake up until 11 tomorrow.
I use this emoticon pretty often, but a lot of people don't understand what it means. I tried to search for an explanation online, but search engines read "=3=" as "3", and return useless hits.
Basically, I use this emoticon to represent a 'pursed lips, there's nothing more I can do' emotion. I like the way that '3' looks like pouty lips.
