Butty
Heard in Waterford and Cork
A good friend, generally male... can also refer to a sandwich (sangwich) filled with chips...
Well butty, giz a chip butty, a few scallops and a battered sausage!
I say, my dearest companion, do furnish me with a bread roll stuffed with fried tubers, several battered potato medallions and a sausage in a crisp golden overcoat. Posthaste.
