Used to show relaxation or being laid back when texting,chatting online,etc.
Mostly used at the start of a sentence, but don't use it tooo much!!!! Just once in a while. If you use it to much then your a dumbass,geek,nerd,etc.
Naturally you will know when to use it, and only certain people can use this powerful word. Seriously.
