A banana bomb was a type of alcoholic beverage, and a favorite of Dave Lister. It was a yellow liquid that appeared in a long, thin glass, filled with cocktail sticks and umbrellas. Before drinking, a firework was set off from it.
Lister was given a banana bomb by the Better Than Life Guide during his game of golf with the Cat in Better Than Life. (RD: Better Than Life, Series II) The original version of this scene before re-shoots can be seen on The Bodysnatcher Collection, where Lister is given the banana bomb amid palm trees.
