Killstreaker 

A girl who purposely aims low and flirts with males in a lower league (especially with simps or white knights) in hopes of adding to their body count to impress a male who is in a higher league.

Lydia is such a Killstreaker. She is only hanging out with James to impress Johnathan.

Killstreak 

A reward given to players in Newer Call Of Duty games after killing a certain amount of enemies without dying. Normally consisting of a support helicopter, dogs, or air-strike. Until Modern Warfare 2 was released and gave players many more rewards for camping and being little pansies abusing care packages and sentry guns. Higher streaks include Harriers that hover with chain guns, predator missiles you control and AC-130 and chain gunships that spawn kill.

Upon camping your ass off to a 25 killstreak you can call in a nuclear warhead to end the game, because by that time the entire server is sick of your shit and at least Infinity Ward is self aware of what they did to a "realistic" war shooter.

Smokeytoke420 with a title and emblem of a weed leaf obtained his AC-130 Killstreak where he proceeded to spawn kill the enemy team as they were punished for not camping.

Killstreak Whore

1. someone who does not play the objective in any Call Of Duty online game, and is only trying to earn killstreak rewards

2. a douche bag who doesnt play to win and only plays to give themself high killstreak rewards such as Chopper Gunner's and AC130's

3. a camper that doesnt care about their team

Dude 1: That guy is not playing the objective hes just camping and building up his streak

Dude 2: I know he is such a killstreak whore!
