The Big Fucking Gun (or more politely, Big Freaking/Fragging Gun) found officially in all of the high-profile id Software games like Doom and Quake. Fires a very large green ball of man-made lightning and then upon impact, the weapon instantly releases a huge spread of energy to anyone that the BFG'er is facing. (Despite how extensive this definition is, it is loose.) In Quake II, the ball of energy will shoot lasers a certain distance for some additional pain.
Newbies hate the weapon, but some veterans consider the BFG a thinking man's weapon (in deathmatch)because of its strange behavior, slow firing rate, and high energy drain.
Grasshopper couldn't hide from ShadowFox's BFG.
Neo was disintegrated by Bar3Star's BFG.

the BFG9000 was the most powerful weapon in the doom video games. it originally stood for "Big Fucking Gun" as explained in the game's design document. the quake games pay tribute to the gun with the BFG10k. in the recent doom motion picture, the gun is denominised on a computer screen as "Bio Force Gun".
