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 

when a guy gets a blowjob from a girl while playing Call of Duty.

the longer the blowjob(in minutes), the larger the killstreak
if she bites during it then "she sent the dogs"
if the guy ejaculates on her then "he used the chopper gunner"

B: "dude mike got a killstreak last night from jenny"
A: "how big was it?"
B: "i think it was a 15 killstreak!"
A: "did she send the dogs or did use the chopper gunner?"
B: "both dude. both."

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!

Professional Killstreak 

A kill counter that shows up on the player's heads-up display that increments by one for each kill. Killstreaks are indicated by a number and a small arrow next to the kill icon, additionally displayed onto the killfeeds of other individuals. Killstreaks messages are broadcast across the entire server once a certain threshold is reached, starting from five kills onward. Professional Kits are the rarest. An eye particle effect is displayed after five kills and intensifies after ten. The effect matches the color of the weapon's sheen in a similar fashion to the Eyelander; when using sword weapons as Demoman, the effect is only presented on his right eye.

Bing soy: a golden pan just dropped in my inventory
Server: 👍
Mr Soy: Ye, I also sold my Professional Killstreak vintage collector's edition battle scarred Hale's own strange golden frying pan.
Server:

Mr Bing: for 20 keys just scam some schmuck
Server people: . . .¿
Bing Soy: *Proceeds to 360 head shot penetrate entire enemy team while jumping off a cliff just to get stuck on an invisible pixel*
