An honorific, "-P" as added to the end of a name, used for mainly Vocaloid and some UTAU users that designates them as a "producer." It is a polite way of showing one's appreciation and respect for a user's music, art or MMD work. The "P" suffix on Piapro, however, can only be obtained by producing many quality Vocaloid works. P-names CANNOT be given to oneself, and DO NOT necessarily mean one has created original music. The topic of the P-name is often one of heavy debate.
