Tonic wine produced by the monks of Buckfast Abbey. The ingredients are unknown, but it contains more caffeine drop for drop than Red Bull. This is a contributing factor to the explosive level of intoxication it induces, and one of its many names (Wreck the hoose juice). It is popular in Scotland and Northern Ireland among neds, chavs and students alike, who appreciate its fine taste and heroin-like buzz.
"Alright mate, you want anything from the offie?"
"Aye get me a battle a Buckfast, I'm ready to knock the fuck clean outta some cunt the nite."
