How did RY4 get its name? what does it stand for?

i love the sample that the kind folks at Freedomsmokeusa put in my order, of RY4. i notice that so many ejuice suppliers have RY4 listed as one of their flavors and have always wondered how RY4 got its name and what does it stand for?

It's the 4th of a line of juices originally made by a company called RuYan, which means "like smoke".
