Funny story when I was playing Call of Duty Black Ops 2.
There was this boy his PSN was " XSilver_BulletX " .
He was quite active in the match and when we returned to the lobby here's how the conversation went.
Me: Hey , what's with the name?
Him : What about it?
Me : Do you know what it means?
Him : Duh! I'm a silver bullet.
Me : * chuckles * No kidding , you are?
Him : What are you on about?
Me : So are you a used silver bullet?
Sadly the lobby was disbanded before he can answer me , and I didn't persue him.
I don't think he actually knew what I was referring to either.
Maybe they should come up with something different to kill vampires with.
