I found myself thinking sociologically when I was talking with my guy friend. I was discussing about how an event in his life changed him. Before this event  he was an ordinary teen; going to  parties, hanging with friends, going to school etc. At home he was use to his mother preparing good food for when ever he got home, he got the usual please, thank you, and sorry from people. After he got in trouble with authorities he had to live in an environment that was new, the environment behind bars.
Desocialization was a process he had to go through because he was so use to the outside rules and rules at home, and then he had to learn to adapt to new ones in jail. In there he had to get use to being an independent guy, because guards were just yelling at all times, and inmates weren't always too polite. His life was pretty much controlled by the prison, so that makes the jail be a total institution. The thing that made his situation worse is that as soon as he had gotten use to life in there, he would have to come back out into the real world, in other words resocialize.
