@Robusto I initially thought it was jocular because its sounds funny in French. Totof can be a nickname for Christophe, teuf-teuf is also a childish onomatopoeic noun for an old car, and
teuf is a well know slang word for party (e.g.
faire la teuf =
faire la fête), a verlan word that became widely used. Teuteuf happens to be based on the last name of the founder of the site and creator of Worldle,
Antoine Teuf so
Te means
Antoine here.
