Expression:
In the vain of ALL YOUR BASE ARE BELONG TO
US, this obscure pop-culture ejaculation finds its origin in the now notorious
NES platformer Bible Adventures. A quirk of the
game's mechanics enabled the player, otherwise entrusted with the safe conveyance of the baby
Moses across the Nile, to commit a most heinous act of infanticide by tossing the little fellow in the drink. The player would then be admonished at the conclusion of the mission that he or she had "forgotten baby
Moses" - no doubt to the delight of the thousands of disgruntled children inclined to such acts of violence by being forced to play Bible Adventures instead of a real video
game.
As an expression, its variety in use is exceeded only by its capacity to offend. Generally, however, "Drown Baby
Moses" is employed referentially in comparisons with gaffes of a similar nature; in disputes over which video
game gaffe is the worst, it is often invoked as a trump card.
