Curiously, the word “mediocrity” appears to be one of the most abused, or wrongly used words by even scholars in Nigeria. All English dictionaries list the word as an “adjective”, a qualifier. But in Nigeria, most users have turned it to a “Proper Noun” and so whoever puts up a mediocre performance as a “mediocre”. There is no such word in any English dictionary. The correct word is “mediocrity”. Anybody that showcases a mediocre performance is called a “mediocrity”. Please check this up in your dictionary. That is the beginning of the war against mediocrity in Nigeria. Note Please: It is not correct to call anyone a “mediocre”. The correct word is “mediocrity”. The word mediocrity is used both as a “Common and Proper Noun”.

I'm sorry but you've even confused me more in your post.
Tnx for bringing it to notice, lemme check my dictionary.
