The title Bonnie and Clyde refers, of course, to the film's two main characters. But it's also what people called them during their time as bank robbers—they weren't primarily known as "the Barrow Gang"; they were known as "Bonnie and Clyde."

And that name has just solidified with their legacy. The phrase "Bonnie and Clyde" conjures up romantic lawlessness—it's almost impossible hear a story about an outlaw couple without coming across a mention of this dynamic duo.
