Shyt stands for Share Your Thing on the website shyt.me.
Some like to use it as "are you shytting me?" or just "shyt!"
It's an interactive tumblr blog where anybody can SHYT their pictures, thoughts, videos and music. People shyt from all over their world and it updates every hour.
Don't just shyt there.. shyt.me!
I have to share this one on shyt.me..
