Get the Justin L mug.
An interesting guy who seems shy at first, but when you get to know him, he is an interesting being. He likes amazing music such as Asking Alexandria and A Day to Remember. He is very nice and has great style! But he does not manage money well because he bought a watch for $250 at the age of 14. And he is very funny!!
That dude is such a Justin L, he bought something for too much even though he hasn't paid his electric bill yet.
