Someone in a multiplayer video game who waits for someone to weaken their enemy and kills them last second so instead of the person who did all the work getting credit the the person who stole gets it.
Person 1: WOW, that's so gay!
Person B: What happened?
Person 1: This noob just stole my kill!
Person B: I fuckin hate Kill Stealers!

Referring to any person who takes the last shot on an enemy character and only the last shot and getting the kill. can be used for any game. Quite prolific on Halo and COD.

A guy or group of people that will wait to you engage a enemy and when the enemies health points are low will kill the enemy with as little as 1 shot or hit and steal your kill and hard work
