John woke up late and missed an important meeting with a client. He knows his manager will be very angry unless there is a strong reason for his absence. So John created a fake excuse. He told his manager that his dog got hit by a car, so they had to rush to a hospital. He said he was in a panic, so he missed the meeting and could not inform the client.
In this case, John created this fake story.
We can say John fabricated this story.
John’s story is a fabrication.
