Imagine if someone took the insult sword fighting part from the first Monkey Island and then made it somewhat more complex - that's The Insult Simulator.

Insults are composed by choosing one of the nine parts of the sentence that are common to both actors at a given moment. When you happen to run out of text, you can afford a short break and start the next round with a new set of words, but that makes you very vulnerable it can very easily happen that the opponent fires a particularly poisonous insult out of his mouth. By focusing on one topic within the same match, combos are connected, which further worsens the opponent's nervous disorder.

Since the vocabulary is limited, it quickly becomes repetitive but for such a nice price it is more than okay. Some phrases are even usable in real-life, trust me, but you didn't hear it from me.
