Bambleboost

(noun) Zindo-Veropean derived. A "bambleboost" is a full-of-food-stains plate too-oft left in the sink whose stains you cannot remove. Food and plate are conjoined now, inseparable. You will scrub and scrub, and even pick at some of the food with your fingernail. Good luck. It's a bambleboost and your efforts are futile.

Example: "We ran out of plates to eat with, so I had to eat my burger on the bambleboost. God dammit."
