Kurapika's initial disrespect for Leorio, "Rewolio"
What exact name is Kurapika using? For me I hear Rioleo, which coincides with the official English translation of the manga. 

Does the actual word mean anything in either English or Japanese? I have not seen the original raws for the particular chapter or scene but the English does not mean anything since it just looks like two parts of his name switched in order (Leo-rio switched to Rio-leo) which was probably his way of showing disrespect by getting the name wrong.
