The site explains itself:
"These are text messages I exchange with my 17 year old cousin Bennett. He is a white boy that thinks he's a Crip, works at Amoco, has a girlfriend named Mercedes, and is one of the most unintentionally funny and brilliant souls on the planet."
Bennett is apparently unaware of the blog. Although judging from his text messages, I'm not sure he would be literate enough to find it even if he knew about it.
