To doom, to condemn to various things that would ultimately result in death, can also refer to daily, harmless activities.
"So, what are we dooming today?"

"Stop dooming at me!"

"What kind of doom is going on over there?"

The act of sniffing the hair of your significant other from behind and subsequently shouting the phrase "Doom!" triumphantly, then acting as though nothing happened.

(originating from the Marvel comics character Dr. Doom's many odd images with the scarlet witch, and his tendency to announce his own name loudly).
Person 1: *sneaks up behind girlfriend with the intent of Dooming*
Girlfriend: "... If you Doom me I /will/ slap you."

A classic first-person shooter (FPS) made by ID Software, the same folks who made quality games like Wolfenstein and Quake.
When playing Doom, watch out for the Cyberdemon, for his rocket-launcher arm can easily kill you.

A game which all players of Counter-Strike, Halo, Quake et al should thank for making the first-person shooter genre what it is today.

Doom is a classic in the true sense of the word. It spawned techniques still used in First-Person Shooters today.
Doom >is greater than> CS+HL+Halo+Quake+Unreal+GoldenEye

All are fantastic games, but Doom outranks them all. After all, Doom is simply legendary among shooter fans, even more so than the seminal CS. Thank Doom, with its crude 2D sprites, blocky graphics and unparalleled gameplay.

One of the greatest FPS of all time. While the game may look outdated today, the gameplay is unparalleled even today. The game plays incredibly well even nowadays. Most fanboys/fags say it sucks because the graphics are bad, but in that case, they need to fuck themselves. Gameplay > graphics.
Halo faggot: omg omg omgomgom Doom sucks halo is BETATAT!!!!1
Normal person: You fail it. Without Doom, Halo would have never existed, so suck your boyfriend's cock and chill out.
