A nickname for a friend who is somewhat religious(Or at least pretends to be) and you play basketball with. Mainly used at summer bible camps and church leagues. This person is usually a ball hog. His 2 moves are run down the lane, charging in similar to a train. Or throwing it up from half court. This person is a real bummer to even be around.
Josh: "Here he comes again!"
Chris: "He never passes the ball, and gets blocked every time."
Dustin: "I really hate him."
Chris: "Don't invite Jesus Train to play ball ever again."
