Salutations, nerds! The topic of this post is roleplaying emotion in tabletop roleplaying games. Mind you, decapitating someone is fine if the situation calls for it.
Roleplaying is a part of every aspect of the game, and it comes to the fore during social interactions. There are two styles you can use when roleplaying your character: the descriptive approach and the active approach. Most players use a combination of the two styles. Use whichever mix of the two works best for you. If your RPG character is not meant to be the type to fly off the handle then insinuation can be a very powerful tool.
Practicing a sharp wit is helpful in a case like this. Take what the person just said to you out of context in a mean way.
Make a snide remark about the thing they are doing that angers your character. The trick here is subtlety and it takes practice. This, like everything else, is a tool in the box to use when the moment calls for it. The bandits stand around the bridge demanding a toll to cross start to close ranks and get in closer to the party. Do they close off, with arms folded?
Do they stand on the balls of their feet ready to spring into a fight? Do they clench their jaw? All of these things convey a very visually different message and each one can be an excellent way to show the path to anger.
