Twinklue

Twinklue (noun): The residual, adhesive-like substance composed of cream filling and cake particles that remains stuck to the inside of a Twinkie wrapper after the snack has been consumed. Often considered a minor but lamentable waste of sweetness, Twinklue is either scraped off for a bonus bite or forever discarded, depending on the eater's dedication to the Twinkie experience.

Example: "Don't throw that wrapper away yet, there's still some Twinklue on it!"
