What is a tall tale?

Answer 1

A tall tale is a story about a larger-than-life character, either fictional or based on a real person who has exaggerated adventures and performs exaggerated feats of daring, strength, courage, and/or intelligence.

Answer 2

A tall tale is a story that is greatly exaggerated over time. === === Another answer: It's a tale that is very hard to believe. My friends tell these all the time. Like, if you say, "My mom MADE me throw my favorite stuffed animal in the fire" it could happen, but is hard to believe.
