 In other words, a drinking problem. Bacchus was the Roman name for Dionysus, the Ancient Greek God of wine and of ecstatic madness. Bacchus gives his name to the bacchanalia, wild and ecstatic festivals of drunken celebration which were originally religious occasions held in secret and celebrated only by women. The word has since come to mean any wild, drunken revelry.
