MIB stands for 'mint in box' — the holy grail condition for collectors of action figures, toys, vintage electronics, and pretty much anything that came in original packaging. If something is MIB, it has never been opened or used and the box itself is in great shape. It's the collector community's highest grade of preservation, and MIB items typically command the biggest premiums on resale. The opposite of that beat-up childhood toy you actually played with.
