Wait, "utouto" could be a play on "uto-uto", which isn't a standard term. Alternatively, maybe it's a phonetic translation of a Japanese phrase. "Uto utu" in Japanese means "my words", but that doesn't directly tie into the rest. The term "suyasuya" might be a misspelling of "suyo" plus "suyo", meaning "yours and yours" in a way, or maybe it's a name of something. Maybe it's a typo for "suyo" as in Aymara/Spanish, but I'm not sure.
