Translations:yupekosi/3/en

From sona pona, the Toki Pona wiki

It is a self-referential joke word. jan Sonja coined yupekosi several years after Toki Pona: The Language of Good, it has a highly specific definition, and it contains an accidental nonstandard letter y, with no official pronunciation. Thus, it retroactively worsens Toki Pona's vocabulary, spelling system, and phonology.
