Of course, the Nigerian arrogance comes out when its bearer is confronted by someone calling him out.
Never mind me, it's you that needs to do some basic research. Not only am I part-Anang with my mum from Ikot-Epene in Akwa Ibom, I speak Ibibio fluently and my mum's name is Ekaette, so I know exactly what it means in Efik, Ibibio and Anang. The issue was never what the English translation of Ekaette is (which practically nobody outside of Cross River and Akwa Ibom would know anyway), but what general idea that name conjures up in contemporary Nigerian culture.
But of course you know this very well and you are doing that passive-aggressive Nigerian thing where you try to win an argument by subtly insulting the other person's intelligence because you know that on the strengths of your own argument, you have no leg to stand on. Carry on, and by all means find it funny.
You won't last 3 years.
