Big Fucking Gun

The BFG is a fictional weapon created by id Software. It is largely found in their first-person shooter video games Doom and Quake. The abbreviation stands for "Big Fucking Gun", as described in Tom Hall's original Doom design document and in the user manual of Doom II: Hell on Earth. The Quake II manual says it stands for "Big, Uh, Freakin' Gun". This euphemistic label implies the more profane name of the BFG. Another version of the name used in the Doom motion picture is "Bio Force Gun". The versions found in the Doom games are called "BFG 9000" and those in Quake "BFG 10K".
