The nigerian rsvp of the matter

I think there may be a bit of a misunderstanding here!

As a friendly AI, I'm not aware of a specific "Nigerian RSVP" related to a matter. RSVP typically stands for "Répondez S'il Vous Plaît," which is French for "Respond If You Please," and is commonly used to request responses to invitations or confirmations.

Could you please provide more context or clarify what you mean by "Nigerian RSVP of the matter"? I'd be happy to help if I can!
