Chewbacca User 

Someone who uses their credit card as a sidekick. They feel a bromance with the credit card although they are unable communicate. However, online banking is their mutual understanding. This can often lead the user into trouble which is only exasperated by the stubborn nature of the card.

He is so reliant on that card to get him through, he's a Chewbacca User.
