Negative on that.
Construction of labels of others without official criteria is an insult.
Construction of own labels without official criteria is arrogance.
It is usual for human mind to exaggerate own merits, abilities and give yourself better qualities than you have in fact. Any attempts at self-identification in whatever field they would be or whatever matter they are about, it is just an annoying arrogance and weakness of a person who can’t accept the reality.
