This kill story is both satsfying and quite funny, well to me anyway.
"So there was this annoying prick on cod4, who kept on giving me grief everytime I killed him he would call me a cheater or every time he killed me he would call me a dickhead or some other swear word".
As the game went on, the guy throws a grenade which kills me, the next thing I know is him shouting across his mike. "Did you fucking see that I threw that from the very end of the map, now I will call you a better player if you could do better noob".
To which I answer "okay"
I throw a grenade from the end of the map and wait next thing I see on my screen is 20 points four people killed with that single grenade and one of them was the guy with the mic.
Now I know that wasn't as impressive as (L3m0n_L1m3) Nine grenade kills, but hearing his reaction across the mic was music to my ears.
Note: When I said the lines "okay before throwing the grenade, I did not expect it to work it was just luck, but still really fucking satsfying luck.
