When a character suddenly becomes afflicted by an intense itch, and they either can't scratch it for fear of certain consequences, or have no means of scratching it on their own. The intensity of the itch will often scale upwards with their inability to take care of it, especially if they are tied up or busy holding a sensitive package full of Explodium.
Nearly always Played for Laughs, the victim of an Inconvenient Itch will often be left begging for their companions (or even antagonists) to help them out. If the afflicted character is left tied up and alone, the humor of the situation may arise from their attempts at contorting their body in an effort to find relief. Though the Inconvenient Itch can hit any part of the body, the nose is a popular target.
