Americans love the underdog.

The underdog is usually defined as someone people tend to cheer for, because they hope he or she can pull off unbelievable feats.

The David and Goliath story in the Old Testament is a perfect example of an underdog story. The young boy David using only a slingshot and a smooth stone along with God's help, succeeded in killing the giant Philistine warrior named Goliath.

Press further defined the term and gave some examples of how it is frequently used in the media on the Feb. 9 edition of CBN News Channel's Morning News.
