Is a pairing in the anime series Yu-gi-oh. This pairing is Bakura (Spirit of the Millenium Ring) and Malik Ishtar (Hikari). There are many other kinds of shippings other than just thiefshipping and some can have the same name for different couples.
In most fanfictions the pairing is given a name that has shipping at the end. Ex: Thiefshipping, Puzzelshipping and so on.
