What is a flea flicker?

A flea flicker is a trick play in American football. It is usually a pass play that starts with the quarterback handing off the ball to a running back, who then quickly tosses it back to the quarterback, who then throws the ball downfield to a receiver. The play is designed to deceive the defense by making them think the running back is going to run the ball, but instead, the ball is passed downfield. The name "flea flicker" is said to come from the motion of a flea jumping backwards and forwards. The flea flicker is considered a high-risk, high-reward play and is often used to gain a big play or score a touchdown.
