First Person Shooter
FPS, Filthy Pigeon Shit. The substance that can usually be found on statues of warheros and other important dead people.
But some people also use FPS as an acronym for First Person Shooter. The kind of game where you see the game from the first person perspective, usually with a hand holding a weapon in the bottom of the screen. Sometimes enhanced by the concept of head bob which can make people feel ill and Throddy happens to dislike.
These games usually come with a multiplayer function which is cool as it allows you to legally shoot your friends while screaming things like BOOM, HEADSHOT!, pwned and who's your daddy? into the microphone as loud as humanly possible, and if you're lucky, louder.
