Someone who hogs, or "whores" all of the valuable weapons in the video game Halo. The term "weapon whore" can be made more specific by replacing the term "weapon" with the valuable object.

n. The birth name of somebody who has changed their name. Most commonly attributed to trans people, but can be attributed to any person who has changed their name. (sometimes written as two words: dead name)

v. 1. To call somebody by their deadname.
v. 2. To out somebody's deadname to the public.

In any given multiplayer First Person Shooter (Especially ones with customiseable content eg CoD 4), a weapon whore is a person who goes around picking up and using people's guns. This is generally due to either: 1. Primary weapon has run out 2. Bad sidearm 3. Beginner and therefore crappy weapons.

Although generally not a bad thing, it can be used as an insult
