The expansion of Internet slang has been furthered through codification and the promotion of digital literacy. The subsequently existing and growing popularity of such references among those online as well as offline has thus advanced Internet slang literacy and globalized it. Awareness and proficiency in manipulating Internet slang in both online and offline communication indicates digital literacy and teaching materials have even been developed to further this knowledge. A South Korean publisher, for example, has published a textbook that details the meaning and context of use for common Internet slang instances and is targeted at young children who will soon be using the Internet. Similarly, Internet slang has been recommended as language teaching material in second language classrooms in order to raise communicative competence by imparting some of the cultural value attached to a language that is available only in slang.
