The BFG9000
The Bio Force Gun is considered to be the original “ultimate” weapon. It’s name, derived from the underwhelming 2005 Doom movie, is first uttered by Dwayne “The Rock” Johnson and — wait a second, the Bio Force Gun? Seriously? Go the fan route and just own the name. “Big Fuckin’ Gun” is more in line with the spirit of the game. There’s also “Big Feckin’ Gun” or “Big Friggin’ Gun.” But anything other than the Bio Force Gun.
Doom is a game about literally going to hell to fight Cyber Demons, Arch Viles, and Spider Mastermind, so a gun worthy of your adversaries is more than necessary. The “Big Fucking Gun 9000” is a large, solid metal gun that fires large green balls of plasma that turns enemies into bloody chunks of gore. And after using it once, everything else will feel like a toy.
