Just wanted to give my genuine belief on why and when the term "beggar" came into the vocabulary of many Northern Ireland fans.
As I understand it, it dates to the Charlton era when the ROI utilised eligibility rules to their great advantage.
Even tho Northern Ireland have since used these rules regularly themselves, the term has stuck.
It might be a hypocritical term and it was probably born out of a jealousy factor of our neighbours during Charlton's remarkable reign.
I do not believe that is used with any more malice than many other terms for rivals - and I accept that many ROI fans do not consider Northern Ireland "big" rivals.
