Our group was going to play Against the Giants a few years ago, just for fun (a few had played it way back when) and were going to use pre-gen PCs. So, my now ex and our friend were driving to game our friend says," I know my brother will play a magic user and use the name Smoke or Cinder," and they told us too when they arrived and the brother wasn't there yet. Later, when we all there, sure enough the brother picked a wizard and changed his name to Smoke. Everybody was rolling around laughing and he got pissed. Then, during the whole game, we kept making fun of his name: "Wow, you really smoked him," etc... He was really ticked then. In the end, we told him to be careful when he used verbs and nouns as names.
