It's not a fallacy. It's more like a "logic smell" that means you should look closer to see if the arguer is jumping to conclusions. If they are you should still investigate, e.g. the chain of events they are describing may have actually happened in history or could be related from personal experience. Affording them merit based on that is probably questionable in terms of formal logic, but it might not be unwise.
