game ruiner 

A party pooper of sorts, specific to the gaming genre: someone that willfully or intentionally would go through great lengths to interfere in the normally fun dynamics - that are the norm when people get together to play games - in a disturbing manner, without remorse (subjective) or shame (ditto).

People described as "Game ruiner" have been known to display further questionable social habits, such as glaring, ogling, gawking, rubbernecking, gloating and even resorting to bitch-slapping when confronted with their behavior.

Eddy: Don't invite Larry anymore..he is such a game ruiner douche-bag!
Brent: Not to worry, he was killed last Sunday when he tried to kick the huge domino's trajectory the local kids had been setting up for three weeks, they sucker-punched him in the nuts and one shot up in his brain, causing an instant rupture as it punctured his skull.
Eddy: .......!

Below is a depiction of the most common characteristics displayed in the average game ruiner's mimic:

Pants Ruiner 

1...someone who continually shits their pants to the point they just wear none, and only wear diapers.

2...a person who goes insane, and the only thing they can think of doing at the time is shit themselves, therefore ruining thier pants, and underwear.

3...a vandal who goes into expensive stores and tries on all of the white pants, and leaves big brown stains in all the asses, in effect ruining them.

4...when in battle, shitting in your BDU's and calling for a medic to come and change them for you so you can keep fighting on, and killing people, not wasting time worrying about clean pants, that's the Medic's job.

Blap is such a Pants Ruiner, he dosn't even come out of the house anymore, and just lines his walls with plastic.

Wang lost his wife and kids to a stampede of Yetti, so when he found out he was a true Pants Ruiner due to the shock of losing his whole family.

Let's go out Pants Ruining tonight, and show those motherfukers who is the real boss.

Specialist Chris Shupe is the greatest Pants Ruiner in the Army, he killed twelve Arabs all while getting his pants changed, what a bad-ass motherfuker.
