Wallet Tuna

Concept invented by two young people at school, tuna in a wallet. It is a mysterious concept, highly subjective, not very objective, and hardly worthy of a concrete definition.

A tuna in a bag, defies reality, and makes us think about life, existence and consciousness.

Tuna in the wallet, in addition to a tuna, and a wallet, is something else.
And that something more is what you want it to be.

-It's your turn to pay.

-Wait what is this? A tuna in your wallet?

-No. This is wallet tuna.
