Internet & Texting Lingo (Feel free to add ones I've missed)

A new language has come about to communicate in a faster, more clever and abbreviated way.  Anyone can start a trend within this lingo; If people like it, it will become popular! On social networks and through texting, people don't wish to be formal.   Texting and social networks are a break from the academic world.  Here's a list of common abbreviations that you may see online or maybe in a text from of friend. (These are ones that I am familiar with.  I am certain that I have missed several)
