One example could be a story about someone getting stuck in traffic for hours and their increasing frustration which is depicted in a rage comic. They start off calm but as the minutes turn into hours, they become more and more enraged.
There could be a true story of someone trying to cook a new recipe. At first, they are excited but as they start, they realize they don't have all the ingredients. Then, things start to go wrong in the cooking process like burning the food or adding too much salt. Their annoyance and disappointment can be the basis of a rage comic true story.
