"When a pirate's marooned, he's a given a pistol with a single shot. One shot. Well, that won't do much good hunting or to be rescued. But after three weeks of a starving belly and thirst, that pistol will start to look real friendly. But Jack escaped the island, and he still has that single shot. Oh, he won't use it, though, save on one man: His mutinous first mate."You ever heard of having a bullet with your name on it? That's what this trope is about. Bob has just betrayed Alice and left her for dead, or maybe he's murdered Alice's whole family, or maybe Alice just really wants Bob to die, so much so that she'll throw in a bit of Poetic Justice and designate a special bullet to be used, just for Bob. This trope is about getting revenge, but it's not enough to simply get revenge. This is a special case. So special that not just any old bullet will do. No, the bullet Alice uses (or even the gun she uses) must be related to the reason Bob must die. Bonus points if the bullet has Bob's name inscribed on it. It's not uncommon for Alice to craft the bullet from special materials as well. Subtrope of It's Personal.
