pulling a Joe

When someone tells a story to one-up the current story being told. Usually involves something so outrageous, you are more interested in why they would tell such a lie than the story being told.

Chris: Hey, Bruce Lee was a great martial artist.

James: Yeah, he would have awesome to meet in person.

Joe: Yeah, my Dad sparred with him, and kicked his ass. My dad was trained by Frank Dux, and was responsible for the game Street Fighter, which is based on him.

James/Chirs: Wow, you sure are pulling a Joe with that one.
