That's funny, Branislav! I initially thought Linisfarne's post said Walmart. The term "wall wart" is a slang term for a type of power supply that transforms AC power from an outlet into DC power. The transformer and other circuitry is contained in a box with the male connectors sticking out of it so the box sits directly on the outlet, so it's hanging on the wall.....uh....like a wart.
