A scav boss in the gameEscape from Tarkov. He's located on the map Interchange, where himself and his scav guards harass all PMC and scav players. He sprays his RPK-16 at anything that moves and throws a bunch of grenades when in combat. He has some pretty good loot if you manage to kill him.
A "Kill Whore" is a term referred to people who only go for kills in video games and do not play the objective. They tend to throw the team off as instead of trying to complete the goal of the specified game mode, they instead try to mop up as many kills as possible and more often than not the players team ends up losing because of it. This term can also simply be used to describe someone who tries to get as many kills as possible regardless of other important stats or just having fun.
Luke stop being a "Kill Whore" we need you to take the flag.
Ahh man that guy is "Kill Whoring" he isn't going on the point, we're probably gonna lose
This isn't even fun anymore, our entire team is "Kill Whoring"
He would suddenly take interest in an old song we all loved years ago, but proceed to just kill the song for the rest of us, playing it over and over to learn the lyrics, and then some because he’s just a psycho like that. I loved that song, I never want to hear it again.
