Jailtacht
A form of Irish used in Northern Ireland that has developed from the H-block hunger strikers, who didn't know or couldn't remember a lot of the Irish language and reinvented it to the best of their knowledge. It is now widely spoken in Northern Ireland and has been accepted as colloquial. It is a play on the word "Gaeltacht", which is used to describe predominantly Irish-speaking regions in Ireland.
"Madadh rua" is the Jailtacht Irish term for fox, as opposed to "madra rua".
