Well, personality wise, he's kind of loud and usually the center of attention. He acts like he has no boundaries, but there are some things that really tick him off, usually when someone insults him and it has actual basis. He's loyal to his friends, but more than willing to make a joke at the expense of others. Therefore, for him, friends can be hard to come by. He also has something against organized religion, so bringing it up with him isnt a great idea.
Also, he has a hard time "getting into" things, but when he is he's completley obsessed. Finslly, when he has no obsession, be tends to bounce around a lot in conversation as his thought processes bring up different things.
