3.
A farmer or someone from an Irish agricultural background. Derived from the Irish term "Muintir na háite" which means locals.

Similarly there's "Munchies" which is the name given by Gaeltacht summer school students to the locals of the gaeltachts.
Look at those munchos in their sand boots and bootcut jeans.
