gyaru-moji
n.— «Japanese girls, however, now prefer to communicate amongst each other using special characters that require more time to input. These characters are called “gyaru-moji” (gyaru is the slang word for girl). The words made from gyaru-moji are a mixture of Japanese syllables, numbers, mathematical symbols and Greek characters. It’s like a secret code used by teenagers; at first glance, the code resembles hieroglyphics.» —“Girl’s Talk!” by Arjen van Blokland Japan.com (Tokyo) Feb., 2004. (source: Double-Tongued Dictionary)
