Dupe Hack

minecraft:dupe_hack is a joke item from Java Edition 23w13a_or_b.

Obtaining
Once the  vote is approved the dupe hack item has a random chance of dropping whenever an entity with chests is killed by a player, e.g. when destroying a minecart with chest with a sword.

It doesn't appear in the creative menu, not even when the option "Operator Items Tab" is enabled, but can be given to the player with  and other commands.

Usage
The dupe hack item can be used to create a limited amount of duplicate items by placing it on a crafting table with any other item. It has a random chance of breaking, controlled by the  vote. This limitation can be mostly bypassed by putting the items in an ender chest first and duplicating the chest.
