Badass Line as you kill...

[Bourne]

I think "I'll see you in hell" is the only thing that makes sense in a situation in which you are given time to speak to your victim.

"It's time to chew bubblegum and kill people. and i'm all out of gum." - Duke Nukem

calmly and coolly after shooting them (preferably in the head): "boom. headshot." - remember it from meet the sniper video from TF2

"hey you look at lot like a dead guy." - remember it from somewhere

"(insert name),I'm hear to tell you that your services are no longer need in the community." - heard it in a couple movies and songs

*Shots the knee*
Missed my target
*Shoots the stomach*
Sorry about that
*Shoots the shoulder/upper arm*
Oh, I'm getting hotter!
*Shoots crotch*
BOOM! Headshot!!
*At this point, I will laugh manically getting closer to my prey. The barrel of my gun slowly inching within point-blank range*
Aww, don't you like my little joke? Well, I have one more for you...the punchline is a killer
*trigger pulled. Target dead*

 

[aarontg]

"did you spend your retirement fund running away from me? ok good" *gun shot*

 

[Delritho]

"Wanna know why Jesus hasn't come back yet? I'm here. *BOOM*"


I'm horrible >_>

 

[MatthewGill]

How about just a simple F*** you, in a casual voice with a bit of a grin on your face. Not like a shout just kinda quiet and simple

 

[Withall]

"Reserve a seat in hell for me, alright?"

"All you wounded...those of you who can....pick yourselves off the ground, HURRY BACK tell your leader, you'll need more men!" Megaman, (Vengeance by the Protomen)

 

[AbsoluteVirtue18]

"Roma Victor!"

or

"Vae Victus!"

That way the last thing they're thinking of before they die is "What the hell did he just-OH GOD MY TORSO!"

A friend of mine said his would be, I'm a lead farmer motherf***er, from Tropic Thunder

"I have come here to chew bubblegum and kick ass, and I'm all out of bubblegum."

 

[LordMoose]

"Look like you need a little more Iron in your diet, Hot Iron!" *dakka dakka dakka*

 

[Cain_Zeros]

Only applies in a specific situation, but it goes a little something like this.

"victim": Please, let me live (or some other such plea for mercy).

Me: I don't spare vermin.

*insert killing "victim" until he is dead here*

 

[Marmooset]

Not a thing.
Either they don't deserve it, or they don't deserve it.

 

[Redratson]

A couple I suppose.
Killinga guy and he falls down "It's a long way down asshole!"
or
killing a person that is not from my country "From America with love, asshole!"

 

[Z(ombie)fan]

nothing, just a sadistic grin letting the asshole know Im enjoying this.
