Rockese

Rockese (also known as YTMNDer slang) is a semi-artificial language originating from Scandinavian YTMND communities in the late-2000s. Rockese is notable as a language that arose as a form of slang initially, before becoming a creole. The English name “Rockese” comes from the “roqqa” subculture that was prevalent among Nordic YTMNDers in the late-2000s.

Overview
Rockese derives words from English (various varieties, including Micronesian, El Kadsreian, Eruowoodian, and Wilsonian), French, Finnish, Norwegian, Swedish, Polish, Japanese, Russian, and other conlangs including Teedish, Toki Pona, and Lojban, as well as other forms of internet slang such as Padonki and Lolspeak.
