What does tutoi sudio mean in English?

"Tutoi", as a verb, is a French term that refers to speaking familiarly with one's friends. That is, literally using the second person singular pronouns "tu" and "toi". Generally, people use the more formal second person plural pronoun "vous" for individuals with less familiar acquaintances, elders, etc.

In this case, then, Tutoi suggests approaching people in an unguarded, friendly manner. Did you mean "Tutoi Studio", or is the Word "sudio" also a mystery?
