A player in a multiplayer game of Halo whose frags are mostly made by sniping from hiding spots. This player often snickers uncontrollably when a frag is executed.
Oooh. Brett is the Brest Sniper! He can snipe every time I respawn. Awh!

Get the Brest Sniper mug.
Background: Faggot hiding in any nook or corner of a Halo/2 map, while painting a portrait of gay.

Definition: A player in a shooter game with an uncontrollable urge to be gay. Consists of: Rapid nose breathing, sniping like a little queer, looking down at the ground, as to not give away his position while looking at your screen. See Faggot Queer Cocksucker etc.
Ex 1 Breast: I'm going to snipe you.
Straight person: Your a little faggot.
Breast: (nose breathing)
Straight person: Damn it! Now I have to respawn.
Ex 2 Breast: I'll kill everyone.
Breast: (Explodes from the blast of my Rocket launcher)
Straight person: Ha! Faggot!

A giant queer who does nothing but snipe in Halo and Halo 2. Loves penis, hates rocket launchers.

Another evident symptom of a brest sniper is laughing through rapid nose-breathing.
"You can't beat the Brest, guy! You can't touch this, I've got mad skills, guy."
