What is the meaning of "sweet frog"?

According to sweetFrog Yogurt, "Frog" is an acronym for "fully rely on God." The name was chosen to emphasize the company's commitment to the local community.

Sweet Frog is a frozen-yogurt company founded in 2009. Founder Derek Cha determined that there was a shortage of frozen-yogurt shops in the eastern half of the United States, so he opened a shop in suburban Richmond, Va. That shop has now grown into a chain of more than 335 stores located across 25 states; it also has international stores. The two frogs that serve as mascots for the chain are named Scoop and Cookie.
