Its roots derive from the yttrium aluminum garnet refined in laser technology. This term refers to one who constantly wears a casual garment commonly made from wool, synthetic fiber, or cotton. It induces warmth on the wearer. Also, a "Yag" is known for their synthetic filamentous biomaterial that grows on the dermis from natural follicles. It is usually found on the head of a yag. Finally, "Yags" are extremely fond of rice and maize products, which leads to the stereotype as one who "beats the rice patty" . Next time you encounter your local Yag, be sure to touch their synthetic filamentous biomaterial and note the lack of chitin.
You: "Hello Yaggy pet name for a Yag, may I notice the lack of chitin in your synthetic filamentous biomaterial?"
Yag: "But of course!"
