Now all Nigerians including professors of english do use this word unseriousness.Now the question is does this word exist? Open your dictionaries and if you can find it then keep using it but if u can't find it use non serious instead of unserious.More words to come.

hahahhaha *falls from statue of liberty*

english is dynamic and we've helped foster this language in so many sense. From pidgin, to other words and 'phrase' we've invented overtime like 'happy christmas/sallah in advance' or 'happy christmas/sallah in arrears ', 'slippers' , ''barb(barbing hair)'', and others i cant remember for now. so, it is not every english word u can find in a dictionay, as some are terms strictly used by professionals in some fields. to be on a safer side, u can use 'not serious'.
