I think this song could be about someone that's like a player. He's "The Bomb" and the effect he causes on whoever he/she goes out with is infamous for it hence the "atomic infamy". Plus the lines "who took advantage and who was defenseless" probably talks about the player and now the narrator's saying that "peppermint girl´s not dumb", meaning that the player should watch out.
