The BFG ("Big Friendly Giant") himself doesn't eat children, as he is a nice vegetarian. Sophie becomes the BFG's friend and they work to rid the world of the nasty human-eating giants.

In the computer game Doom and its sequels, the BFG-9000 (BFG standing for "Big (Expletive Deleted) Gun") is a massive plasma weapon; it is the most powerful weapon in the game, capable of destroying nearly any player or enemy with one hit. Most subsequent first person shooters implemented similar weapons, but few of them were quite as notorious or ridiculous as the BFG-9000.
