The royal ship of Queen IronYuppie in AH.com Wars. So called because of its shiny reflective metallic appearance.
(Note for non-Britons - Bacofoil is a famous brand of tinfoil well-known for providing tacky special effects, such as 1930s 'futurey clothes' and the original Cybermen from Doctor Who. Not a kind of salad oil, for those who believe it's pronounced bac-of-oil).
Unlike the real Star Wars prequel trilogy, which has three different (unnamed) royal ships, the Bacofoil featured in Episode 1 and then was blown up at the beginning of Episode 2. It was replaced by the HMS Tinfoil (possibly named after Matt's roommate Tinfoil).
