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"
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."
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.
